Hey. I'd be thankful to anyone who can help me with the following:
Consider a binomial random variable with n = 9 and p = .3. Let x be the number of successes in the sample.
a. Find the probability that x is exactly 2.
b. Find the probability that x is less than 2.
c. Find P(x > 2).
d. Find P(2 x 4).
