Problem Solving s5

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 ?

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 ?

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:

For an initial screening of an admission test, a candidate is given fifty problems to solve. If the probability that the candidate can solve any proglem is (4)/(5) , then the probability that he is unable to solve less than two problem 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 3/4 b.1/2 c.2/3 d.1/3

A problem is given to 3 students.Their chances of solving it individually are (1)/(3),(1)/(4) and (1)/(5). The probability that the problem will be solved is (A) (2)/(5) (B) (3)/(5) (C) (4)/(5) (D) (1)/(5)

The probabilities of A , B and C solving a problem independently are respectively (1)/(4) , (1)/(5) , (1)/(6) . If 21 such problems are given to A , B and C then the probability that at least 11 problems can be solved by them is

A problem is given to three students A, B and C, whose probabilities of solving the problem indrependently are (1)/(2), (3)/(4) and p respectively, if the probability that the problem can be solved is (29)/(32) , then what is the value of p ?
