4. Consider events A and B. Let C be the event that where either A occurs or B occurs, but not both. Show P(C)- P(A) P(B) - 2P(An B). Compute P(An B) and P(AlB) chance of being male. Let A the event that there is at most one female. Let B be 5. Consider events A and B. Suppose P(A)0.2, P(B)0.3 and P(AU B)-0.4. 6, A cat has a litter of kittens. Each kitten has a 50% chance of being female and 50% the event that the litter contains both sexes. Are A and B independent? Explain.
