Food express is running a special promotion in which customers can win a free gallon of milk with their food purchase if there is a star on their receipt . so far, 129 of the first 138 customers have not received a star on their receipts. what is the experimental probability of winning a free gallon of milk? a, 3/46 b, 43/46 c, 11/138 d, 43/138

Experimental probability is the number of times an event occurs out of the number of trials performed (flipping a coin would be a trial, getting heads would be an outcome. say you perform 10 trials and get 6 heads, the experimental probability of getting heads would be 6/10). since 9 out of 138 have won free milk, the experimental probability of winning milk is 9/138 or 3/46.

its 4.6

explanation: i got the answer right.
