The Alamo – this is a binomial probability problem B(7, 0.773) P( x ≤ 3) = 0.0513
(Use calculator : binomcdf (7, .773, 3)
Fiesta, Texas – this is a discrete probability distribution problem. We know that Flibbergibit took 3 or 4 minutes to park & walk to the entrance. If he took 3 minutes to park & walk, it took 1 minute to wait in line. If he took 4 minutes to park & walk, he waited 0 minutes in line. We use our probability rules now:
OR (0.31)(0.22) + (0.35)(0.03) = 0.0787
Eliminate The Alamo.
