1. During a promotion, Christina's department store offers a mailing "scratch a winner - discount savings." After customers select the items they wish to purchase, they scratch their discount sticker from the mailing to determine the discount they will receive. The scratch wheel is divided into 12 slices. Six slices are red and award a 10% discount, three slices are white and award a 20% discount, and two slices are blue and award a 40% discount. The remaining slice is gold and awards a 100% discount if the customer scratches that slice!
ANSWER: What is the probability that a customer gets at least a 40% discount?
ANSWER: = .25 (3/12)
MY PROBLEM IS THAT I DONT UNDERSTAND HOW THE ANSWER IS 3/12 IF THE PROBLEM SAYS ONLY TWO SLICES ARE 40%. I BELIEVED THAT IT WOULD HAVE BEEN 2/12 BUT IS WRONG. CAN YOU PLEASE EXPLAIN WHY IS IT 3/12
