Question

In emails to monthly readers of a newsletter 3% of the emails come back undelivered. The editor predicts that if he sends out 12,372 emails, he will receive 437 notices for undelivered email. Do you agree with his predictions?

Answer 1

Prediction is not correct.

Explanation:

We are given the following in the question:

Percentage of emails that come back undelivered = 3%

Total number of emails = 12,372

Number of undelivered notice = 437

Verification:

`3\%* 12372\\\\=(3)/(100)* 12372\\\\=371.16\\\\eq 437`

He will receive approximately 371 undelivered email.

Thus, the prediction that editor will receive 437 notices for undelivered email is not correct.
