The probabilities of two events X and Y are 0.4 and o.6 respectively. The conditional probabilities of three other events A, B and C occurring, given that X or Y has already occurred, are:
A B C
X 0.2 0.5 0.3
Y 0.6 0.1 0.3
What are the conditional probabilities of X and Y occurring, given that A, B or C has already occurred?
