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
