Answer/Step-by-step explanation:
Given:
A gas station offers a lucky draw to customers. Each time you spend more than $20 on gas, you can make a draw to win a prize. The probability of winning a prize is 1/12 suppose you buy gas 4 times.
To Find:
what is the probability of you winning a prize each time?
Solve:
Since, it given that you buy gas 4 times. Thus that means:
1/12 × 1/12 × 1/12 × 1/12 or 1/12⁴
Now solving it:
1/12 × 1/12 × 1/12 × 1/12 = 1/20736
Which also means (0.0048%) in decimal form since, 1 divide by 2076 equal to 0.0048%
