During its grand-opening week, Stickler's bicycle shop offers a "wheel of discount savings." After customers select the items they wish to purchase, they spin the wheel to determine the discount they will receive. The 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! 40 10 100 10 10 20 30 40 1) The probability that a customer gets at least a 40% discount is A) 3/12. B) 2/12. C) 0.0625. D) 9/12.
