Question

The college hiking club is having a fund raiser to buy new equipment for fall and winter outings. The club is selling Chinese fortune cookies at a price of $1 per cookie. Each cookie contains a piece of paper with a different number written on it. A random drawing will determine which number is the winner of the dinner for two at a local Chinese restaurant. The dinner is valued at $35. Since the fortune cookies were donated to the club, we can ignore the cost of the cookies. The club sold 521 cookies before the drawing. (a) Lisa bought 15 cookies. What is the probability she will win the dinner for two

Answer 1

0.0288 or 2.88%

Explanation:

(a) So the probability of winning 1 dinner-for-two prize out of 521 possible cookies, knowing that Lisa bought 15 cookies is the probability that fortune cookie falls into the 15 out of 521 possible cookies, which is:

15 / 521 = 0.0288 or 2.88%
