The odds of event A happening are 1:3. The probability of event B happening is 40%. If events A and B are mutually exclusive events, then determine P(A or B).
Homework Answers
P(Event A) = 1/(1 + 3) = 1/4 = 0.25
P(Event B) = 0.40
Hence,
P(A or B) = P(A) + P(B) - P(A and B) = 0.25 + 0.40 - 0 = 0.65
Add Answer to:
The odds of event A happening are 1:3. The probability of event
B happening is 40%....

Suppose event A occurs with probability 0.26 and event B occurs with probability 0.29.
Events A and B are mutually exclusive. Suppose event A occurs with probability 0.26 and event B occurs with probability 0.29. If event A or event B occurs cor both), what is the probability that A occurs?

Sometimes probability statements are expressed in terms of odds. The odds in favor of an event A is the following ratio. P(A)/P(not A) = P(A)/P(A^c) For instance, if P(A) = 0.60, then P(A^C) = 0.40 and the odds in favor of A are 0.60/0.40 = 6/4 = 3/2, written as 3 to 2 or 3:2. Show that if we are given the odds in favor of event A as n:m, the probability of event A is given by the following....

Two events, A and B, are mutually exclusive and each has a nonzero probability. If event A is known to occur, the probability of the occurrence of event B is A.One B.Any positive value C.Zero D. Any value between 0 to 1 Suppose that the probability of event A is 0.2 and the probability of event B is 0.4. Also, suppose that the two events are independent. Then P(A∩B) is: a.P(A) = 0.2 b. P(A)/P(B) = 0.2/0.4 = 0.05 c....
