The probability of' the solving a problems in mathematics of three students are 1/3,1/5,1/6 . If they try to solve the problem together, find the probability that the problem is solved by at least one student.

a problem on mathematics is given to three students A,B,C whose probabilities of solving it are 1/3,2/5and 3/4 . Find the probability that the problem is solved.

The probabilities of solving a problem by three students A,B,C are 3/7,3/8,and 1/3 if all of them try independently find the probability that the problem is not solved.

Probability of solving specific problem independently by A and B are (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.

A problem in mathematics is given to three students A, B and C and their respective probability of solving the problem is (1)/(2),(1)/(3) and (1)/(4) . Then the probability that the problem is solved, is -

A problem on mathematics is given to three students A, B, C whose probabilities of solving it are (1)/(3), (2)/(5) and (3)/(4) respectively. Find the probability that the problem is solved.

A problem in mathematics is given to two students A and B. The probability of solving the problem is (3)/(4) and (5)/(7) respectively. If the probability that the problem is solved by both of them is (2n)/(21) , then the value of n is -

The probabilities of A , B and C solving a problem independently are respectively (1)/(4) , (1)/(5) , (1)/(6) . If 21 such problems are given to A , B and C then the probability that at least 11 problems can be solved by them is
