Question

The probability of a New York teenager owning a skateboard is 0.37, of owning a bicycle is 0.81 and of owning both is 0.36. If a New York teenager is chosen at random, what is the probability that the teenager owns a skateboard or a bicycle?

Answer 1

let, P ( skateboard ) = 0.37 PC bicycle) = 0.81 plowning both) = 0.36 using formula as PCA ORB)= PCAD+PCB) - PCANB) - PC skateboard Or bicycle) Po Skateboard) + PC bicycle) – Poconing both) = 0.37 + 0.8- 0136 = 0.82 P(skateboard OR bicydel = 0.82
