 A small life insurance company has determined that on the average it receives 3 death claims per day. Find the probability that the company receives at least 2 death claims on a randomly selected weekend.

 Let us we have two series such that X and Y. If, Cov(X,Y)=9 and Var(X)=8 and Var(Y)=15 then find the correlation coefficient and interpret it.

 The machine produce 15 products in one day (9 of them good, 6 of them defective) a) If we select randomly 5 products, find the probability of at least one of them will be defective. b) If we selected 10 products during a day, how many of them should have been expected to be non-defective.

 A basketball player makes 60% of her free throws. We put her on the free-throw line and ask her to shoot free throws until she misses. Let X = the number of free throws the player takes until she misses.  What is the probability that the player misses her first free throw within the first 3 attempts?  What is the probability that her first miss will not occur within the first 3 attempts?  What is the probability that she will not miss a shot within her first 5 attempts?

 Suppose that X has the following discrete distribution,  P(X=1)= 0,1 P(X=4)= 0,2  P(X=2)= 0,2 P(X=5)= 0,3  P(X=3)= 0,2 Find the median?

 A basketball player makes 60% of him 3 points throws, a) When he throw 5 balls, find the probability of 2 of them will be scores. b) If he throws 50 ball, then what's the expected scores of them?
