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 receipts. What is the experimental probability of winning a free gallon of milk?
A.3/88
B.15/88
C.73/88
D.1/78
The number of customers who have received a star on their receipt is 264 - 219 = 45.
The experimental probability of winning a free gallon of milk is the number of customers who received a star on their receipt divided by the total number of customers:
45/264
Simplifying this fraction by dividing both the numerator and denominator by 3 gives:
15/88
Therefore, the answer is B. 15/88.
To find the experimental probability of winning a free gallon of milk, we need to determine the number of customers who have received a star on their receipts.
The number of customers who have not received a star on their receipts is given as 219 out of the first 264 customers. To find the number of customers who have received a star, we can subtract this from the total number of customers:
Number of customers who have received a star = Total number of customers - Number of customers who have not received a star
Number of customers who have received a star = 264 - 219
Number of customers who have received a star = 45
Now, we can calculate the experimental probability of winning a free gallon of milk by dividing the number of customers who have received a star by the total number of customers:
Experimental probability = Number of customers who have received a star / Total number of customers
Experimental probability = 45 / 264
To simplify this fraction, we can divide both the numerator and the denominator by the greatest common divisor, which is 3:
Experimental probability = (45 / 3) / (264 / 3)
Experimental probability = 15 / 88
Therefore, the experimental probability of winning a free gallon of milk is 15/88. The correct answer is B.
To find the experimental probability of winning a free gallon of milk, we need to divide the number of customers who received a star on their receipt by the total number of customers.
The number of customers who received a star on their receipt can be calculated by subtracting the number of customers who did not receive a star from the total number of customers. So, the number of customers who received a star is 264 - 219 = 45.
Now, we divide the number of customers who received a star by the total number of customers. The total number of customers is 264.
Experimental probability = (number of customers who received a star) / (total number of customers)
Experimental probability = 45 / 264
To simplify the fraction, we can divide both the numerator and denominator by the greatest common divisor which is 3.
Experimental probability = (45 ÷ 3) / (264 ÷ 3)
Experimental probability = 15 / 88
Therefore, the experimental probability of winning a free gallon of milk is 15/88.
So, the correct answer is B. 15/88.
