Question

A light-rail service claims to be on time 98% of the time. If Jeanette takes the light-rail 40 times one month, how many times can she predict she will be on time? Is the light-rails claim accurate if she is late 6 times?

Answer 1

Answer:

So she can predict that she will be 39 out of 40 times she will be on time.

Step-by-step explanation:

The light rail service claims that it on time 98% of the time .

Given the girl takes light rail service 40 times per month .

Assuming the statement given by the light rail serve is correct 98% of 40 times the girl reaches on time , which is 39 times.

So she can assume that she will be 39 out of 40 times she will be on time.

No the light rails is not accurate if she was late 6 times out of 40 times in a month. Because  by the statement given by light rail service she can miss a maximum of 1 time .
