A and B are two students. Their chances of solving a problem correctly are `1/3 and 1/4`, respectively If the probability of their making a common error is, 1/20 and the obtain the same answer, then the probability of their answer to be correct is

A problem is given to three students whose chances of solving it are 1/4, 1/5 and 1/3 respectively. Find the probability that the problem is solved.

A problem in Mathematics is given to two students A, B and their chances of solving the problem are 2/3, 3/4 respectively. The probability that exactly one of them solves the problem is

A problem in mathematics is given to three stdents A,B,C and their chances of solving the problem are 1/2 , 1/3 and 1/4 respectively . The probability that the problem is solved is

A problem is given to that three students whose chances of solving it are 1/5,1/5,1/3 respectively. Find the probability that the problem is solved.

In a race the probabilities of A and B winning the race are 1/3 and 1/6 respectively. Find the probability of neighter of them winning the race.

The probability of solving a problem of mathematic for A and B are 1/3 and 1/5 respectively. If both try the problem, find the probability that the problem will be solved.

The probabilities of A, B and C solving a problem are 1/3, 2/7 and 3/8 respectively. If all the thee try to solve the problem simultaneously, find the probability that exactly one of them can solve it.

A and B are two independent events.The probability that both A and B occur is 1/6 and the probability that neither of them occurs is 1/3.Then the probability of the two events are respectively:

The probabilities of solving a problem correctly by A and B are (1)/(8) and (1)/(12) respectively. Given that they obtain the same answer after solving a problem and the probability of a common mistake by them is (1)/(1001) , then probability that their solution is correct is (Assuming that if they commit different mistake, then their answers will differ)

A problem in mathematics is given to 3 students whose chances of solving it are 1/2; 1/3; 1/4 . What is the probability that the problem is solved?
