Given : A department store offers a promotion for the customers who have receipts with a minimum purchase of Php 2,000 worth of shopping goods. They get a chance to spin two identical spinners
with 8 partitions, each of which is labelled with different prizes.
The customer wins if the two spinners stopped at the same labelled price.
To Find : Find the probability of winning the prize
Solution:
Let say 8 different partitions on each spinners are A , B , C , D , E , F , G , H
Total possible outcome = 8 * 8 = 64
The customer wins if the two spinners stopped at the same labelled price.
= { (AA) , ( BB) , (CC) , (DD), (EE) , (FF) , (GG) , (HH) |
= 8 ways
the probability of winning the prize = 8/64
= 1/8
the probability of winning the prize = 1/8
