1. Suppose you have 3 bags containing only apples and oranges. Bag A has 2 apples and 4 oranges, bag B has 8 apples and 4 oranges, and bag C has 1 apple and 3 oranges. You pick 1 fruit (at random) from each bag.

a) What is the probability that you picked exactly 2 apples?

b) Suppose you picked 2 apples but forgot which bag they came from. What is the probability that you picked an apple from bag A?

Can you also explain your reasoning behind it.

I have two bags. Bag 1 contains 3 green balls, while bag 2 contains 2 green balls. I pick one of the bags at random, and throw 5 red balls in it. Then I shake the bag and choose 4 balls (without replacement) at random from the bag. (a) If bag 1 is picked, what is the probability that there are exactly 2 red balls among the 4 chosen balls? (b) If bag 2 is picked, what is the probability...

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. )
