Assuming the binomial distribution applies with a sample size of n = 15, find
a. the probability of 5 or more successes if the probability of a success is 0.30

c. the expected value of the random variable if the probability of success is 0.40
d. the standard deviation of the random variable if the probability of success is 0.40 |
