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 ______

Mahesh has certain number of problems with him. He can solve some fixed number of problems every hour. After solving for 5 hours, he is left with 384 problems. If he had solved for 10 hours, he is left with 144 problems to solve. Find the number of problems with Mahesh initially.

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 probabiltiy that A alone solves it is ______

For an initial screening of an admission test,a candidate is given fifty problems to solve.If the probability that the candidate can solve and problem is (4)/(5), then the probability that he is unable to solve less than two problems is:

The probability that A can solve a problem is 4/5 and B can solve it is 2/3 .If both attempt the problem what is the probability that exactly one of the problem gets solved ?

A student can solve 2 out of 4 problems of mathematics, 3 out of 5 problem of physics, and 4 out of 5 problems of chemistry. There are equal number of books of math, physics, and chemistry in his shelf. He selects one book randomly and attempts 10 problems from it. If he solves the first problem, then the probability that he will be able to solve the second problem is 2/3 b. 25/38 c. 13/21 d. 14/23
