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? 1. More than 10% of the coupons say “Win a free burger.” 2. The proportion of coupons that say “Win a free burger” is equal to 0.50. 3. 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.” 4. If we randomly select one customer who has received a prize coupon, there is a 25% chance that coupon says “Win a free small drink,” “Win a free ice cream cone,” or “Win a free burger.” 5. If we randomly select one customer who has received a prize coupon, there is a 15% chance that coupon says “Win a free ice cream cone” or “Win a free burger.”
