Suppose that F and G are two events with P( F ) = 0.1, P( G ) = 0.3, and P( G  F )=0.5. What is P( F or G )? 4. Consider the joint distribution of X and Y : X =1 X =2 Y =1 0.2 0.3 Y =2 0.1 0.4 What is E( X  Y =1)? What is E( Y  X =2)? 5. Consider tossing a pair of fair dice two times. Consider the following events: A = odd number on the first roll, B = even number on the second roll. Are events A and B disjoint? Are events A and B independent? 6.
