Question

The probability that a person visiting a zoo will see the girafee is 0.72, the probability that he will see the bears is 0.84 and the probability that he will see both is 0.52. Select the correct answer from above options

Answer 1

P(to see girafee)=0.72 P(to see bear) = 0.84 P(to see girafee and bear) = 0.52` P (to see girafee or bear) = P(girafee)+P(bear)-P (girafee and bear) = 0.72 + 0.84-0.52 =1.04 which is not possible. Hence statement is false.
