Using a random selection of 18 people from the population measure Rh factor, what is the probability of each of the possible outcomes

how would I determine the probability that:

1.) 3 are Rh negative.

2.) none are Rh negative

3.) more than 3 are Rh negative

also how would I create histograms for these questions?
