60 points!!! ASAP A store hands out 900 reward cards. Customers scan their cards in the store to find out what reward they recei
diamong [38]

Answer:

100 customers

Step-by-step explanation:

Note that when you say "The probability that a customer receives a $25 gift card is 19", I assume you mean 1/9, not 19 because probability cannot exceed 1.

There are 900 reward cards in total, which means 900 customers have a chance to receive a reward. Out of these 900 customers, 1/9 of them receive a $25 gift card, so in order to find how many receive a gift card, we do:

(1/9) * 900 = 100

Thus, 100 customers receive a $25 gift card.
