From a box of fruit containing 47 oranges and 1 apple a random sample of 2 pieces of fruit has been selected without replacement. Let X be the number of oranges and Y be the number of apples in the sample. What will the correlation of X and Y be? (Hint the variance of X and Y same. Covariance is just negative of these variances. )

How many ways are there to select 6 pieces of fruit from a huge box containing apples, oranges, lemons, and grapefruits? (The order in which the pieces are selected does not matter, only the type of fruit and not the individual pieces matter, and there are a lot more than 6 pieces of each fruit in the box.)
