A company checks washers at a plant and records 588 defective washers out of 2,940 checked. What is the experimental probability, P (defective) ?

Total number of washers that were checked = 2940

Number of defective washers = 588

Probability of a washer being defective can be calculated as:

P (defective) = (Number of defective Washer) / (Total Number of Washers)

Using the values we get:

P (defective) = 588/2940

P (defective) = 1/5 = 0.2

Since, the figures given are the results of an actual experiment/survey, the resulting probability will be the experimental probability.

Thus, the experimental probability of a washer being defective is 0.2
