An undergraduate student believes that the probability of getting an admission from graduate school A is 55 percent, and the probability that he gets an admission from graduate school B is 50 percent. Also he believes that the probability of getting admission from both schools is 45 percent. Calculate the probability that he will get admission at least from one of these schools 0.45 0.55 0.6 0.4

Solution

12.

P(A U B) = P(A) + P(B) - P(A n B)

=0.60 + 0.55 - 0.35

= 0.8 [ANSWER, D]
