Determine whether each of the following scenarios describes a geometric setting. If so, define an appropriate geometric random variable. a. A popular brand of cereal puts a card bearing the image of 1 of 5 famous NASCAR drivers in each box. There is a 1/5 chance that any particular driver’s card ends up in any box of cereal. Buy boxes of the cereal until you have all 5 drivers’ cards. b. In a game of 4-Spot Keno, Lola picks 4 numbers from 1 to 80. The casino randomly selects 20 winning numbers from 1 to 80. Lola wins money if she picks 2 or more of the winning numbers. The probability that this happens is 0.259. Lola decides to keep playing games of 4 Spot Keno until she wins some money.
