1. (a) Two events A and B are such that P(A)=1/4,P(A/B)=1/2,and P(B/A)=2/3.Are A and B independent events? Are A and B mutually exclusive events? (b) How many sample of size 4 can be drawn without replacement from the population 0,3,6,3,18?compute the sampling distribution of the mean, then identify the relationship between the population and sampling distribution standard deviations?
Suppose that the events A, B and C are mutually independent with P(A)=1 /2, P(B)=1/3 and P(C)=1/4. Compute P(AB U C). Note: the answer is 3/8. Show the steps to get to the final answer.

If A and B are independent events with ?(?) = 1 4 and ?(?) = 2 3 , calculate the following probabilities: a. ?(?|?) b. ?(? AND ?) You roll a dice twice. Let A be the event that you roll a dice and the number shown is 5. Let B be the event that you roll a dice and the number shown is 2. Interpret ?(?|?) in words. If ?(? ??? ?) = 0.15, and ?(?) = 0.6, what...
