Question

A quality control inspector rejects 253 can openers from a batch of 19,354. What is the experimental probability that a can opener will pass inspection?

Round your answer to the nearest hundredth.

Answer 1

The answer is 0.99
19354-253=19101
19101/19354=0.987
Now round to nearest 0.99

Answer 2

0.99

Explanation:

To find the experimental probability, divide the number of can openers that passed inspection by the total number of can openers in the batch:

Passed inspection:
`19,354 -253=19.101`
Experimental probability:
`19,101`÷
`19,354=0.987`
Which rounded to the nearest hundredth is 0.99
