Tricky problems;27+27÷3(1+8)=?; Can you solve this?

A and B try to solve the problem independently. The probability that A solves the problem is (1)/(2) and that B solves the problem is (1)/(3) . Find the probability that : (a) Both of them solve the problem (b) The problem is solved.

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

A can solve a problem with probability (1)/(2)B and C can solve the problem with probabilities (2)/(3) and (2)/(3) respectively.A problem is given to the team of A,B and C.What will be the probability that the team will be the problem?

Given the probability that A can solve a problem is 2/3 and the probability that B can solve the same problem is 3/5. Find the probability that none of the two will be able to solve the problem.

The probabilities that A and b can solve a problem independently are 1/3 and 1/6 respectively. If both try to solve the problem independently, find the probability that: (i) problem will be solved (ii) both can solve the problem.

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.

If 3 men or 5 women can solve a problem in 3 days then in how many days can 1 man and 2 women's solve the same problem
