1.	In a certain population, 10% of the people arerich, 5% are famous, and 3% are rich and famous. Then find the probabilitythat a person picked at random from the population is either famous or richbut not both.
Answer» Correct Answer - 0.09 Here, `P(R)(10)/(100) =0.1, P(F) = (5)/(100) = 0.05` `P(F nn R) = (3)/(100) = 0.03` Therefore, the required probability is `P(R) + P(F) - 2P(F nn R) = 0.1 + 0.05 - 2(0.03) = 0.09`
