From a box of fruit containing 62 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. )
