A fast-food restaurant attaches prize coupons to the cups used to serve large drinks. Seventy percent (70%) of the coupons say “Play Again,” 15% say “Win a free small drink,” 10% say “Win a free ice cream cone,” and the rest say “Win a free burger.”  Given what you know about probability and probability models, which one of the following statements must be correct? Group of answer choices Less than 10% of the coupons say “Win a free burger.” If we randomly select one customer who has received a prize coupon, there is a 45% chance that coupon says “Win a free small drink,” “Win a free ice cream cone,” or “Win a free burger.” If we randomly select one customer who has received a prize coupon, there is a 5% chance that coupon says “Win a free small drink” or “Win a free ice cream cone.” If we randomly select one customer who has received a prize coupon, there is a 20% chance that coupon says “Win a free ice cream cone” or “Win a free burger.” The proportion of coupons that say “Win a free burger” is equal to 0.50.
