The chance that Om can solve a certain problem is 1/4 , the chance that Jay can solve it is 2/3. Find the probability that the problem is solved if they both try.
Probability that Om can solve a problem = 1/4 Probability that Om cannot solve a problem = 3/4 Probability that Jay can solve a problem = 2/3 Probability that Jay cannot solve a problem = 1/3 The probability that the problem will not be solved:- ⇒ 3/4 x 1/3 = 1/4 the probability that the problem is solved :- 1 – 1/4 = 3/4
