To find:
The probability that anyone item is defective from a 1, 000 sampled items which has four defectives.
Answer to Problem 1CR
Solution:
The probability that any one item is defective from a 1, 000 sampled items which has four defectives is
Explanation of Solution
Definition:
If an experiment has n mutually exclusive and equally likely outcomes, and if s is the favorable outcomes, then the probability of any event E denoted as
Calculation:
Consider a sample of 1, 000 items from an assembly line. This sample reveals four defective items from these sampled items.
Define E to be the event that the item is defective. So there are 4 favorable outcomes. Use the probability formula and calculate the probability.
Thus, the required probability is
Final statement:
The probability of getting defective item from 1, 000 sampled items is
