For the disjoint events A and B in a sample space , we know that P(A

For the disjoint events A and B in a sample space Ω, we know that P(A ∪ B) = 5∕6, 4P(A) + P(B′) = 1.

Then, the probabilities of the events A and B are, respectively, equal to

(a) P(A) = 1∕6, P(B) = 2∕3

(b) P(A) = 2∕3, P(B) = 1∕6

(c) P(A) = 1∕3, P(B) = 1∕2

(d) P(A) = 1∕2, P(B) = 1∕3

(e) P(A) = 1∕18, P(B) = 7∕9.
