1 point A student is randomly selected in a university Event

(1 point) A student is randomly selected in a university. Event A denotes that the student uses MasterCard, while event B denotes that the student uses Visa Card. Given that P(A) -0.51, P(B) 0.43 PCAnB) = 0.18, which option defines the probability that the selected student has neither of the cards. A) P(A\'nB\') = 0.76 B) P(AuB), 0.24 C) P(A,nB\') = 0.82 D) P(AnB)\' = 0.82

Solution

Note that

P(A u B)\' = 1 - P(A U B)

= 1 - [P(A) + P(B) - P(A n B)]

= 1 - (0.51 + 0.43 - 0.18)

= 0.24 [ANSWER, B]
