Question

​Thirty-six percent of customers who purchased products from an​ e-commerce site had orders exceeding 110. If ​17% of customers have orders exceeding 110 and also pay with the​ e-commerce site's sponsored credit​ card, determine the probability that a customer whose order exceeds 110 will pay with the sponsored credit card.

Answer 1

The right solution is "0.5".

Explanation:

According to the question,

P(pay with the sponsored credit card | order exceeds $110)

=
`(P(Pay \ with \ the \ sponsored \ credit\ card\ and\ order\ exceeds\ 110))/(P(order \ exceeds \ 110))`

=
`(P(A \ and \ B))/(P(A))`

By putting the values, we get

=
`(0.17)/(0.34)`

=
`0.5`

Thus, the above is the right solution.
