Quizplus · Accepted Answer

To find the probability that a vacationer will visit at least one of these attractions, we need to add the probability of visiting CN Tower and SkyDome and then subtract the probability of visiting both so that it is not counted twice.

P(CN Tower or SkyDome) = P(CN Tower) + P(SkyDome) - P(CN Tower and SkyDome)
P(CN Tower or SkyDome) = 0.5 + 0.4 - 0.35
P(CN Tower or SkyDome) = 0.55

Therefore, the probability that a vacationer will visit at least one of these magnificent attractions is 0.55.
