Question

The school cafeteria has two meal options in the main line today: a grilled chicken sandwich or a spicy fried chicken sandwich. In one lunch period, 60 people order the grilled chicken sandwich, and 90 people order the spicy fried chicken sandwich. 40 of the people who ordered the grilled chicken sandwich got a chocolate milk to drink. If the sandwich choice and the drink choice are independent, how many people got a chocolate milk given that they ordered the spicy fried chicken sandwich?

Answer 1

60 people got the chocolate milk who ordered spicy fried chicken sandwiches.

Explanation:

Out of 60 people who ordered grilled chicken sandwich, got the chocolate milk to drink = 40

Therefore, the percentage people who got the chocolate milk out of 60 people =
`(40)/(60)* 100`

= 66.67%

If the sandwich choice and drink choices are independent, then the number of people given chocolate drink who ordered spicy fried chicken sandwich

= 66.67% of 90

= 60

Therefore, 60 people got the chocolate milk who ordered spicy fried chicken sandwiches.
