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, 219 of the first 264 customers have not received a star on their receipt. So far, 147 of the 156 costumers have not received a star on their receipts. What is the experimental probability someone will win a free gallon of milk?

Answer 1

3/52

Explanation:

The experimental probability of winning a free gallon of milk will be calculated as under -

It is given that, total number of outcomes = 156

Non-winning customers = 147 (it is given in the question)

Thus, the winning customers will be = Total outcomes - Non-winning customers

Expected winning customers = 156 - 147 = 9

The probability is calculated as -

Probability (Winning customer) = winning customers/total customers

Probability (Winning customer) = = 9/156 = 3/52

Answer 2

3/52

Explanation:

The experimental probability of winning a free gallon of milk will be calculated as under -

It is given that, total number of outcomes = 156

Non-winning customers = 147 (it is given in the question)

Thus, the winning customers will be = Total outcomes - Non-winning customers

Expected winning customers = 156 - 147 = 9

The probability is calculated as -

Probability (Winning customer) = winning customers/total customers

Probability (Winning customer) = = 9/156 = 3/52
