Probabilities of solving a specific problem in dependently by A and B are 1/2a n d1/3 respectively. If both try to solve the problem independently find the probability that : The problem is solved Exactly one of them solves the problem.

If k lt 0 , then the number of roots of the equation ke^(x)-x=0 , is

While solving the problem of sex determination in large number of insects, it was observed that

Probability of solving specific problem independently by A and B are 1/2 and 1/3 respectively. If both try to solve the problem independently, find the probability that (i) the problem is solved (ii) exactly one of them solves the problem.

A computer solved several problems in succession. The time it took to solve each successive problem was the same number of times smaller than the time it took to solve the preceding problem. How many problems were suggested to the computer if it spent 63.5 min to solve all the problems except for the first, 127 min to solve all the problems except for the last one, and 31.5 min to solve all the problems except for the first two?

Probabilities of solving a specific problem independently by A and B are 1/2\ a n d1/3 respectively. If both try to solve the problem independently, find the probability that (i) the problem is solved (ii) exactly one of them solves the problem.

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

Rewriite problem by either distributings or factoring and then solve. Question 3, 4, and 5 have no numbers in them, therefore, they can't be solved with a calculator. Q. (6times57)+(6times13) =___
