Question

a website offers a couple such that each customer has a 15% chance of getting the coupon everyday they visit the site. aya visits the website for 6 consecutive days. what is the probability that wya will be offered the coupon on at least one of the days she visits the site?

Answer 1

62.285% chance Aya gets a coupon at least once in 6 days.

The probability that Aya will get the coupon on at least one day is 1 - (0.85)^6 = 0.62285.

Here is the breakdown of the calculation:

The probability that Aya will not get the coupon on one day is 1 - 0.15 = 0.85.

The probability that Aya will not get the coupon on 6 consecutive days is 0.85 ^ 6.

The probability that Aya will get the coupon on at least one day is 1 - 0.85 ^ 6.

Therefore, the probability that Aya will get the coupon on at least one day is 0.62285.
