Step-by-step explanation:
The probability that the customer will pay with debit card = 50%
The percentage of customers who use coupons 30% and 35% pay with debit card.
Now calculate the probability that the same person will use coupon:
P[Uses coupons | Pays with Debit card] = P[Uses coupons and pays with debit card] / P[ Pays with debit card]
= 0.3 * 0.5 / 0.35
= 3/7 or 0.4286 or 42.86%
