![(a) An insurance company sells several types of insurance policies, including auto policies and home- owner policies. Let Aj be those people with an auto policy only, A2 those people with a homeowner policy only, and A3 those people with both an auto and homeowner policy (but no other policies). For a person randomly selected from the companys policy holders, suppose that P(A) 0.3, P(A2)-0.2, and P(A3)-0.2. Further, let B be the event that the person will renew at least one of these policies. Say from past experience that we assign the conditional probabilities PUBA) 0.6, P(BA2) 0.7, and P(BIA3) -0.8. Given that the person selected at random has an auto or homeowner policy, what is the conditional probability that the person will renew at least one of those policies?

![(b) From an ordinary deck of 5 playing cards, cards are to be drawn successfully at random and without replacement. Find the probability that the third spade appears on the sixth draw. [2] (c) The continuous random variable X is uniformly distributed between O and 4. Suppose that a random sample of 15 observations is selected from this distribution. What is the approximate probability distri bution of Y = 2X-6 (where X denotes the sample mean of the random variable X)?[2] (d) Let X be the number of heads in three tosses of a fair coin. Find the variance of x. [2]](http://img.homeworklib.com/questions/c5702e70-89a7-11eb-a819-0f35aecd958c.png?x-oss-process=image/resize,w_560)
