In a contest, Ama, Kwaku, and Musa are asked
to solve a problem. The probabilities that they
solve the problem correctly are, respectively,
5, 3 and 3. Calculate the probability that:
(1) none of them solves the problem
correctly;
(11) at least one of them solves the problem
correctly;
(II) only one of them solves the problem
correctly.
(WASSCE)

Let the probabilities be P(A)=1/2 P(B)=1/3 and P(C)=1/6 We need to find the ... With the recent market drop, it's the perfect time to stock up on these 5 stocks under ... Since we know that the problem will be solved if at least one of them solves the problem. ... P( A and B) =1/6 and the probability that neither of them occur is 1/3.
