WebIf P(A) = 0.5, P(B) = 0.4, and P(A or B) = 0.8, are A and B mutually exclusive? 20. If P(B) = 0.6, find P(B c). 26. Determine whether events A and B are mutually exclusive. A: Jayden has a math class on Tuesdays at 2:00. B: Jayden has an English class on Tuesdays at 2:00. 40. In a statistics class of 30 students, there were 13 men and 17 women. WebP(A B)=P(AB)/P(B) by definition, P(A)=P(AB)/P(B) if A and B are independent, hence P(A)P(B)=P(AB); this is sometimes given as the definition of independence. Rearranging this last equation as P(AB)/P(A)=P(B), we see that if P(A B)=P(A), then also P(B A)=P(B). Examples: If P(A)=.5, P(B)=.4, and P(AB)=.2, then P(A B)=.2/.4=.5 = P(A) and

Assuming that events A and B arise from independent random processes, i. … WebTo find: The probability of getting a 2 or 3 when a die is rolled. Let A and B be the events of getting a 2 and getting a 3 when a die is rolled. Then, P (A) = 1 / 6 and P (B) = 1 / 6. In this case, A and B are mutually exclusive as we cannot get 2 and 3 in the same roll of a die. Hence, P (A∩B) = 0.
