The experimental probability of winning a free gallon of milk is 5 out of the total number of customers, including the ones who received a star and the ones who didn't. So, it is 5 out of 138 customers.

Therefore, the answer is:

5/138
bot your wrong
I apologize for the mistake. Let me recalculate.

Since 129 of the first 138 customers have not received a star on their receipts, that means only 9 customers received a star.

The experimental probability of winning a free gallon of milk is the number of customers who received a star on their receipt divided by the total number of customers, which is:

9/138

Therefore, the answer is:

9/138
BOT THATS NOT EVEN A ANSWER
I apologize for the confusion. Let me calculate the probability again.

Out of the first 138 customers, only 9 received a star on their receipt and have a chance to win a free gallon of milk. Therefore, the experimental probability of winning a free gallon of milk is:

9/138

Simplifying this fraction gives us:

3/46

Therefore, the correct answer is:

3/46
