A container has 50 marbles. 22 are blue, 11 are red, 8 are yellow, and the rest are white. Suppose we sample 5 marbles in a row, with replacement.

a) What is the probability that exactly 4 of them are blue?

b) What is the probability that at least one is yellow?

c) What is the probability that fewer than 2 are white?

d) How many would you expect to be red?



Any help would be greatly appreciated!
