A movie theater gave away coupons for smallmediumand large drinks. Customers could randomly pull a coupon from a box that held 75 small drink coupons , 125 drink coupons , and 150 large drink coupons . What is the probability that the first customer to pull a coupon from the box got a medium drink coupon ?

Respuesta :

Answer: 35.7%

Step-by-step explanation:

First find out the total number of all coupons in the box.

= 75 + 125 + 150

= 350 drink coupons

There are 125 medium coupons so the probability that the first customer will pick a medium one is:

= Number of medium coupons / Number of total coupons

= 125 / 350

= 35.7%
