You are given the following information about events A, B, and C. • The probability of event A occurring is 0.5. • The probability of only event A occurring is 0.24. • Events B and C are mutually exclusive. • The probability of C occurring is 1.5 times the probability of B occurring. • The probability of none of the events occurring is 0.18. • The probability C occurring and A not occurring 0.17. Find the probability of event B NOT occurring. 0.699 0.791 0.722 0.768 0.745
The events of A and B are mutually exclusive. Suppose P(A) 0.2 and P(B) = 0.1. What is the probability of either A or B occurring? What is the probability that neither A nor B will happen? Next page TOSHIE
Suppose we conduct a study about the effect of a certain trait on the recovery of a person from a certain illness. Let the probability that a person recovers from a certain illness be equal to 0.4 and the probability that a person possesses the trait be equal to 0.3. If getting an illness and possessing the trait are independent events, what is the probability that at least 10 out of the 15 survivors possess the trait?
