It is observed that 25% of the cases related to child labour reported to the polic station are solved. If 6 new cases are reported, then the probability that atleast 5 of them will be solved is

A problem is given to three children, whose chances of solving it are 1/6 , '1/4' and 1/5 , what is the probability that : At least one of them may solve. it.

A problem is given to three children, whose chances of solving it are 1/3 , 1/5 and 1/6 , what is the probability that : At least one of them may solve. it.

A problem is given to three students, whose chances of solving it are : 1/3, 1/5 and 1/6 respectively. Find the probability than exactly one of them may solve it.

A man speaks truth in 60% cases. He throws a die and reports that it is a six . The probability that it is actually a six is

Probability of A, B and C of solving a problem are (1)/(5), (1)/(6) and (1)/(3) espectively. If they all try to solve the problem then find the probability that exactly one of them will solve the problem.
