A manufacturer of spark plugs has a goal of producing less than 2% defective ones. Of the last 8,000 spark plugs, 13 were defective

13 / 8000

Step-by-step explanation:

Given:

Total number of Spark plugs = 8,000

Total number of defective Spark plugs = 13

Probability of defective spark plug = ?

Computation:

Probability of happening an event (P. e) = Number of favorable outcomes / Total Number of outcomes

= 13 / 8000

Therefore, Probability to get a defective spark plug is 13/8000
