PROBLEMS ON 1D

A problem in statistics is given to four students A, B, C and D. Their chances of solving it are (1)/(3), (1)/(4), (1)/(5) and (1)/(6) respectively. What is the probability that the problem will be solved?

The problems which seek to maximise (or minimise) profit (o r cost) from a general class of problems called A) optimization problems B)customization problems C)Both A and B D) none of these

The probability of solving a problem of mathematic for A and B are 1/3 and 1/5 respectively. If both try the problem, find the probability that the problem will be solved.

The probability of solving a specific problem independently by A and B are (1)/(3) and (1)/(5) respectively. If both try to solve the problem independently, find the probability that the problem is solved.

The world's problem No. 1 today is :

Two Block Problem - 1

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.
