Question

The probability that a randomly selected person has high blood pressure (the event H) is P(H) 0.3 and the probability that a randomly selected person is a runner (the event R) is P® 0.3 The probability that a randomly selected person has high blood pressure and is a runner iso.. Find the probability that a randomly selected person has high blood pressure and is not a runner. a 0.2 b) 0.6 c0.3 d) 0.7 e 0.4 fONone of the above

Answer 1

$P(H)=0.3,~P(R)=0.3,~P(H\cap R)=0.1.\\ P(H\cap R^c)=P(H)-P(H\cap R)=0.3-0.1=0.2.\\ Henc~Option~a.$
