What does the abbreviation Stet mean?
Stet is an obelism, used by proofreaders and editors to instruct the typesetter or writer to disregard a change the editor or proofreader had previously marked. It is a form of the Latin verb sto, stare, steti, statum.
What does upside down V mean in algebra?
While there are more sophisticated meanings in higher mathematics, most of the time you will see the inverted v it means the operation “to the power of.” For example, 5^2 is 5 to the power of 2, or 5 squared, which is 5×5=25. The operation “to the power of” is called “exponentiation”.
What does the U in math mean?
union of sets
What is upside down U in math?
Upside down ‘U’ i.e, ‘∩’ means the intersection between two sets. This set will contain all elements of A that also belong to B (or equivalently, all elements of B that also belong to A). The symbol means intersection between two sets. The intersection of two sets can be defined as follows.
What is a ∩ B?
In mathematics, the intersection of two sets A and B, denoted by A ∩ B, is the set containing all elements of A that also belong to B (or equivalently, all elements of B that also belong to A).
What does P AUB mean?
P(A U B
What does ∩ mean in probability?
The probability of the intersection of Events A and B is denoted by P(A ∩ B). If Events A and B are mutually exclusive, P(A ∩ B) = 0. The probability that Events A or B occur is the probability of the union of A and B.
What does the U symbol in probability mean?
uniform distribution equal
What does P AnB ‘) mean?
P(A∩B) is the probability that events A and B both happen. Basically ∩ means ‘and’. U is the union, so P(A U B) means the probability that either A or B occurs, or both; it’s the probability that at least one of the events happens. P(AUB)=P(A)+P(B)-P(A∩B), if I’m remembering right.
How do you get p AnB?
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.
What does P Ba mean in probability?
P(B|A) means “Event B given Event A” In other words, event A has already happened, now what is the chance of event B? P(B|A) is also called the “Conditional Probability” of B given A.
What does ∪ mean in probability?
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.
What is the best definition of probability?
1 : the quality or state of being probable. 2 : something (such as an event or circumstance) that is probable. 3a(1) : the ratio of the number of outcomes in an exhaustive set of equally likely outcomes that produce a given event to the total number of possible outcomes.
What is the OR rule?
The ‘or’ rule If you want one outcome or another outcome then you add their probabilities together. For example: For two events A and B, p (A or B) = p (A) + p (B)
