When events are mutually exclusive and we want to know the probability of getting one event OR another, then we can use the OR rule. P(A or B) = P(A) + P(B) for mutually exclusive events.

Given “A and B,” where A and B are either true (non-zero) or false (0), “and” is multiplication. For example, the truth of “it's raining and I'm wearing a red shirt and …” is multiplicative: I have to evaluate all the inputs to find if the statement is true. Given “A or B,” we get addition.

Roughly speaking (not always 100% true!), in probability, the word or translates into addition, while and translates into multiplication. The added assumptions are: you can only add if the two events are disjoint. you can only multiply if the two events are independent.

In mathematics, the word “or” means “one or the other or both”. In other words, the statement is only false if “it will rain” is false and “it will snow” is also false. When one or both parts of an “or” statement are true then the whole statement is true.

Unions. The symbol we use for the union is ∪. The word that you will often see that indicates a union is "or".

Inclusion-Exclusion Rule: The probability of either A or B (or both) occurring is P(A U B) = P(A) + P(B) - P(AB). Conditional Probability: The probability that A occurs given that B has occurred = P(A|B). In other words, among those cases where B has occurred, P(A|B) is the proportion of cases in which event A occurs.

, I was on my high school math team. Here are the two definitions as used in probability: “OR” means that you are calculating the probability that either event A alone, event B alone or both events A and B occurred. “AND” means that both events A and B have to occur.

The probability of events A and B occurring can be found by taking the probability of event A occurring and multiplying it by the probability of event B happening given that event A already happened. If events A and B are independent, simply multiply ( ) by ( ).

Addition and multiplication both have an interpretation in probability theory but it's slightly more complicated than: + is OR, * is AND. Better rules would be: If two events A and B are disjoint, then P(A OR B)=P(A)+P(B), but P(A AND B)=0. If two events A and B are independent, then P(A AND B)

An odds ratio (OR) is a measure of association between an exposure and an outcome. The OR represents the odds that an outcome will occur given a particular exposure, compared to the odds of the outcome occurring in the absence of that exposure.

Conditional probability: p(A|B) is the probability of event A occurring, given that event B occurs. Joint probability: p(A and B). The probability of event A and event B occurring. It is the probability of the intersection of two or more events. The probability of the intersection of A and B may be written p(A ∩ B).

intersectionThe intersection of two or more sets is the set of elements that are common to every set. The symbol ∩ is used to denote the intersection. When events are independent, we can use the multiplication rule for independent events, which states that P(A∩B)=P(A)P(B) P ( A ∩ B ) = P ( A ) P ( B ) .

The union of two sets contains all the elements contained in either set (or both sets). The intersection of two sets contains only the elements that are in both sets. The intersection is notated A ⋂ B.

In probability, there's a very important distinction between the words and and or. And means that the outcome has to satisfy both conditions at the same time. Or means that the outcome has to satisfy one condition, or the other condition, or both at the same time.

“OR” means that you are calculating the probability that either event A alone, event B alone or both events A and B occurred. “AND” means that both events A and B have to occur.

To help students in the United States remember this order of operations, teachers drill the acronym PEMDAS into them: parentheses, exponents, multiplication, division, addition, subtraction. Other teachers use an equivalent acronym, BODMAS: brackets, orders, division and multiplication, and addition and subtraction.

The ⇒ symbol is often used in text to mean "result" or "conclusion", as in "We examined whether to sell the product ⇒ We will not sell it". Also, the → symbol is often used to denote "changed to", as in the sentence "The interest rate changed.

Wedge (∧) is a symbol that looks similar to an in-line caret (^). It is used to represent various operations. In Unicode, the symbol is encoded U+2227 ∧ LOGICAL AND (HTML ∧, · &and,, &wedge, ) and by \wedge and \land in TeX. The opposite symbol (∨) is called a vel, or sometimes a (descending) wedge.

If the event of interest is A and the event B is known or assumed to have occurred, "the conditional probability of A given B", or "the probability of A under the condition B", is usually written as P(A|B) or occasionally PB(A).

α (Alpha) is the probability of Type I error in any hypothesis test–incorrectly rejecting the null hypothesis. β (Beta) is the probability of Type II error in any hypothesis test–incorrectly failing to reject the null hypothesis.

Formula for the probability of A and B (independent events): p(A and B) = p(A) * p(B). If the probability of one event doesn't affect the other, you have an independent event. All you do is multiply the probability of one by the probability of another.

These are used in set notation. U stands for union. And upside down U stands for intersection.. .For example given the set A = {1, 2, 3} and B = {3, 4, 5} Then A U B = {1, 2, 3, 4, 5} and A intersection B = { 3 }

Union is denoted by the symbol ∪ . The general probability addition rule for the union of two events states that P(A∪B)=P(A)+P(B)−P(A∩B) P ( A ∪ B ) = P ( A ) + P ( B ) − P ( A ∩ B ) , where A∩B A ∩ B is the intersection of the two sets.

“OR” means that you are calculating the probability that either event A alone, event B alone or both events A and B occurred. “AND” means that both events A and B have to occur.

Wrong answer Its letters stand for Brackets, Order (meaning powers), Division, Multiplication, Addition, Subtraction. It contains no brackets, powers, division, or multiplication so we'll follow BODMAS and do the addition followed by the subtraction: This is erroneous.

It's not MDAS. It's actually DMAS, which means division, multiplication, addition and subtraction. In mathematics, this rule is followed which means in an equation or a problem, the order of simplification will be in the above format.

The Four Probability Rules P(A or B)=P(A)+P(B)−P(A and B) In set notation, this can be written as P(A∪B)=P(A)+P(B)−P(A∩B). Whenever an event is the complement of another event, the Complementary Rule will apply. Specifically, if A is an event, then we have the following rule.

In the recent events of the Boruto manga, Sasuke Uchiha ended up losing his Rinnegan as it was stabbed by none other than Boruto Uzumaki and while this decision makes sense to some, it doesn't sit well with quite a lot of fans.

Madara founded Konoha with Hashirama. Sasuke is the least descentant of the Uchiha, aka the current head of the clan after he fathered Sarada, but he is not directly related to Madara despite both being form the same family.

Satyrs were characterized by their ribaldry and were known as lovers of wine, music, dancing, and women. They were companions of the god Dionysus and were believed to inhabit remote locales, such as woodlands, mountains, and pastures.
