The probabilities of a problem being solved by two students are `(1)/(2)` and `(3)/(4)`. Then the probability (i) of problem being solved and (ii) problem not being solved is.

The probability of a problem being solved by 3 students independently are (1)/(2), (1)/(3) and alpha respectively. If the probability that the problem is solved in P(S), then P(S) lies in the interval (where, alpha in (0, 1) )

The probabilities of solving a problem by three students A,B and C are 1/2, 1/3 and 1/4 respectively. The probability that the problem will be solved, is

The probability of solving a problem by three students X, Y and Z is 1/2, 1/3 and 1/4 respectively. the probability that the problem will be solved is :

A problem is given to three students A, B and C whose probabilities of solving the problem are (1)/(2),(3)/(4) and (1)/(4) respectively. What is the probability that the problem will be solved if they all slove the problem independently?

The probability of solving a problem by three students are 1/3,1/4,1/5 . Find the probability that the problem will be solved if all three students try the problem simultaneously.
