Question

Suppose a card is drawn from a deck of 52 playing cards. What is the probability of drawing a 5 or a king? 156 14 f None of the above Review Later Question 12 The probability that a randomly selected person has high blood pressure (the event H) is P(H) 0.2 and the probability that a randomly selected person is a runner (the event R) s P(R) 0.4. The probability that a randomly selected person has high blood pressure and is a runner is 0.1. Find the probability that a randomly selected person either has high blood pressure or is a runner or both. a) 0.6 b) 0.9 c) 0.4 d) 0.5 e) 0.8 f None of the above

Explanation / Answer

Answer - 1: P(Drawing 5 or a king) = (4 + 4)/52 = 8/52 = 2/13

Option D is correct.

Answer - 12: P(Either high BP or runner or both) = P(High BP) + P(Runner) - P(Both) = 0.2 + 0.4 - 0.1 = 0.5

Option D is correct.
