Beacon Hill Trees & Shrubs currently has an inventory of 10 fruit trees, 8 pine trees, and 14 maple trees. It plans to give 4 trees away at next Saturday’s lawn and garden show in the city park. The 4 winners can select which type of tree they want. Assume they select randomly.

a. What is the probability that all 4 winners will select the same type of tree?

b. What is the probability that 3 winners will select pine trees and the other tree will be a maple?

c. What is the probability that no fruit trees and 2 of each of the others will be selected?
