9 There are seven candidates running for the election. In how many ways could they select four of them to a) attend the game, b) attend the rally, c) attend the cabinet meeting, and d) attend the dinner with the Governor?

11 Find the mean of the given probability distribution. Round appropriately. x P(x) 1 0.15 2 0.29 3 0.43 4 0.13

12 See problem 11 above. Find the standard deviation.

18 If a binomial experiment were conducted with 12 trials, with probability of success on each trial 0.6, find the minimum usual value if the experiment were conducted many times.

04 Use the table below. Find the probability a randomly selected individual is down given that they are red.updownblue4879red5768

17 If a binomial experiment were conducted with 12 trials, with probability of success on each trial 0.6, find the variance if the experiment were conducted many times.

20 Assume poisson. Given that mean is 6.4, find P(X>5).

14 Assume binomial: n = 8, p = 0.45, find P(4)

P is the point (3,5), Q is the point (9,3).M is the midpoint of PQ. PQR is a triangle. The vector QM is  () Vector QR is(-13) The vector PR is()
