1. There are 16 pea seeds in a packet available to a gardener. Seven of the peas areWando, 4 are Maestro, and 5 are Lincoln. To test the soil of a specific garden for growing peas, the gardener picks 8 of these seeds at random to plant in that garden. Let X be the number of Lincoln seeds and Y be the number of Wando seeds chosen. Find the joint probability mass function of X and Y, the conditional probability mass function of X given that Y = y, and P(X = 3 | Y = 3).
