17

Step-by-step explanation:

In this case we know that there are a total of 340 recipients and they tell us that of 20 recipients only 1 receipt of the 40% discount.

So what you need to do is apply the probability to the total recipients, like so:

Number of recipients with 40% = Total recipient * probability of 40%

N = 340 * (1/20)

N = 17

Which means that the best projection is that only 17 people out of those 340 will benefit from the 40% discount.
