The total number of customers is 156. Since 147 of them did not receive a star on their receipts, that leaves 156-147=9 customers with stars on their receipts.
The experimental probability of winning a free gallon of milk is the number of customers who received stars (9) divided by the total number of customers (156):
9/156
Simplifying this fraction gives us:
3/52
So the answer is D. 3 over 52.
