A problem in Mathematics is given to three students whose chances of solving it are `1/3, 1/4, and 1/5`
(i) What is the probability that the problem is solved ?
(ii) What is the probability that exactly one of them will solve it ?

Text Solution

Verified by Experts

The correct Answer is:
`= 12/60 + 8/60 + 6/60 = (12 + 8 + 6)/(60) = (overset(13)(cancel26))/(60) = 13/30`
