Probability Dice Problem -1

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.

Statement-1: The probability that A and B can solve a problem is (1)/(2) and (1)/(3) respectively, then the probability that problem will be solved (5)/(6) . Statement-2: Above mentioned events are independent events.

A, B and C were given a problem in Mathematics whose respective probabilities of solving it are (1)/(2),(1)/(3) and (1)/(4) . The probability that the problem is not solved is ______

The odds against solving a problem by A and B are 3 :2 and 2 : 1 respectively, then the probability that the problem will be solved, is

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 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?
