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.

Option A is correct i.e. the experimental probability of winning a free gallon of milk is [tex]\frac{3}{46}[/tex].

What is experimental probability?

The experimental probability of an event occurring is the number of times that it occurred when the experiment was conducted as fraction of the total number of times the experiment was conducted.

Formula for experimental probability

[tex]P(E) = \frac{number of times an even occur}{Total number of trials}[/tex]

According to the given question

Number of customers who received a star on their receipts = 138-129=9

Therefore,

The experimental probability of winning a free gallon of milk is given by

[tex]P(E) = \frac{number of people who receive stars}{total number of people}[/tex]

[tex]P(E) =\frac{9}{138}[/tex][tex]=\frac{3}{46}[/tex]

Hence, option A is correct.
