Volume of sphere = 4/3 * π * r^3.

The constants don't matter because we're doing it by ratio, what matters is that volume is proportional to r^3. The radius is 3x larger, so the volume will be 3^3 = 27 times larger.

Therefore the volume of the smaller sphere is 729 / 27 = 27 in^3.

"1 indicating a coupon and all other outcomes indicating no coupon"
Probability is (number of successful outcomes) / (number of possible outcomes)

Theoretical Probability of rolling a 1: 1/8 

Experimental Probability of using coupons: 4/48  =  1/12

So, the experimental probability of a customer using a coupon (that is, 1/12) is smaller than the theoretical probability of rolling a 1 (that is, 1/8).
