Mohan can solve 90% of the problems of his mathematics book while sohan can solve 70% of them. If a problem is selected at ramdom, what is the probability that none of them will solve the problem?
Hi Shaleen,
The Probability that none of them solve is:
P(Mohan doesn't solve & Sohan doesn't solve) = 1/10 * 3/10 = 3/100 = 3% chance that none of them solve it.
Hope that helps.
Best Regards,
Ashwin (IIT MadraS).
