Question 4:
(a) Suppose a random number is picked from
1, 2, 3, 4, 5, 6, 7, 8, 9, 10
and all outcomes are equally likely. Let A be the event that the number is less than 5, and let
B be the event that the number is an odd number.
1) Are A and B independent?
2) Given that an odd number is picked, what is the probability that the number is '1'?
