To celebrate the opening of a new store, when a customer gets to the register, they get to spin a prize wheel that is equally di
rodikova [14]

Answer:

81 / 1024

Step-by-step explanation:

Given that :

Wheel is divided into 4:

Hence, probability of winning either 10%, 20%, 30% or 50% = 1/4

Probability of winning 50% discount = 1/4

Probability of not winning 50% discount :

1 - 1/4 = (4 - 1) /4 = 3/4

Hence, probability that 50% is won by 5th customer :

(3/4) * (3/4) * (3/4) * (3/4) * (1/4)

= (3/4)^4 * (1/4)

= (81 /256) *(1/4)

= 81 / 1024
