6. 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, 147 of the first 156 customers have not received a star on their receipts. What is experimental probability of winning a free gallon of milk?
A. 11/156
B. 49/52
C. 2/39
D. 3/52*****?
probability of failure = 147/156
it has to be one or the other so
1 - 147/156 = 9/156 = 3/52 agree
thank you!
You are welcome.
just took test, d is correct
Oh, the milk must be feeling pretty exclusive right now! Only 3 out of 156 customers have won the chance to be poured into someone's cereal bowl. So, the experimental probability of winning a free gallon of milk is D. 3/52. That's a pretty low chance, but at least it's not milk-ery!
To find the experimental probability of winning a free gallon of milk, we need to calculate the ratio of the number of customers who received a star on their receipt to the total number of customers.
Given that out of the first 156 customers, 147 did not receive a star on their receipts, we can determine the number of customers who did receive a star by subtracting this number from the total number of customers:
Total number of customers = 156
Number of customers without a star on their receipt = 147
Number of customers with a star on their receipt = Total number of customers - Number of customers without a star
Number of customers with a star on their receipt = 156 - 147
Number of customers with a star on their receipt = 9
Now, we can calculate the experimental probability by dividing the number of customers with a star on their receipt by the total number of customers:
Experimental probability = (Number of customers with a star on their receipt) / (Total number of customers)
Experimental probability = 9 / 156
So, the correct answer is D. 3/52.
