Question

The Florida Tourist Commission selected a random sample of 200 people that attended one or more concerts during the first weekend in April of 2010. The survey revealed that 120 concert goers went to Orlampa Skydome and 100 went to the Bithlo Megaplax. Calculate the probability that a selected concert goer during the same weekend next year will go to either the Orlampa Skydome OR the Bithlo Megaplax?

P(Orlampa Skydome or Bithlo Megaplax) = P(Orlampa Skydome) + P(Bithlo Megaplax) - P(Orlampa Skydome AND Bithlo Megaplax)

Book Notation: P(A or B) = P(A) + P(B) - P(A and B)

How did you arrive at your answer?

Two performers want you to represent them but you can only represent one of them. Your income would be based on a commission based on total ticket sales. The following data shows the revenue generated during their last six concerts and a list of the concerts that the performer cancelled. When a performer cancels, those ticket sales are lost, not to mention the bad publicity a cancelled show generates.
