What does U mean in probability?
P(A∪B) Formula. The symbol "∪" (union) means "or". i.e., P(A∪B) is the probability of happening of the event A or B. To find, P(A∪B), we have to count the sample points that are present in both A and B.
What does N mean in probability?
n: sample size or number of trials in a binomial experiment. ... p̂: sample proportion. P(A): probability of event A. P(AC) or P(not A): the probability that A doesn't happen. P(B|A): the probability that event B occurs, given that event A occurs.
What is the U symbol in stats?
The symbol 'μ' represents the population mean. The symbol 'Σ Xi' represents the sum of all scores present in the population (say, in this case) X1 X2 X3 and so on.
What does upside down U mean in probability?
The circles A and B represent sets. "Intersect" is represented by an upside down U. The intersection is where the circles overlap. "Union" is represented by a right-side up U.
