ms. sue that is a link to a different question
the a
correct
To find the experimental probability of winning a free gallon of milk, you need to determine the ratio of the number of customers who received a star on their receipts to the total number of customers.
In this case, out of the first 138 customers, 129 did not receive a star on their receipts. So, the number of customers who received a star on their receipts is 138 - 129 = 9.
Therefore, the experimental probability of winning a free gallon of milk is 9/138.
However, this fraction can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 3.
So, the simplified fraction is 3/46.
Hence, the correct answer is 3/46.
