A problem in mathematics is given to three students `A ,B ,C` and their respective probability of solving the problem is 1/2, 1/3 and 1/4. Probability that the problem is solved is a.`3//4` b. `1//2` c. `2//3` d. `1//3`

A problem is given to three students A,B,C then probability of solving is 0.6,0.5 and 0.7 respectively. What is the probability that is solved:

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 ?

A problem is Mathematics is given to three sutdents whose chance of solving it are in the ratio 6:4:3 respectively. What is the probability that (i)the problem is solved(ii)what is the probability that none of them could solve the problem.

A and B try independently to solve a problem. Probability that A solves it is (1)/(3) and that B solves is (3)/(5) . Find the probability that the problem is solved

Three persons work independently on a problem. If the respective probabilities that they will solve it are 1/3, 1/4 and 1/5, then find the probability that not can solve it.

If odds against solving a question by three students are 2:1, 5:2, and 5:3, respectively, then probability that the question is solved only by one student is a. 31//56 b. 24//56 c. 25//56 d. none of these

Probability of solving specific problem independently by A and B are and (1)/(2) and (1)/(3) respectively. If both try to solve the problem independently, find the probability that i. the problem is solved ii. exactly one of them solves the problem

Four persons independently solve a certain problem correctly with proabilities 1/2,3/4,1/4,1/8. Then the probability that the problem is solved correctly by at least one of them is
