Question

A container contains 10 diesel engines. the company chooses 8 engines at​ random, and will not ship the container if any of the engines chosen are defective. find the probability that a container will be shipped even though it contains 2 defectives if the sample size is 8.

Answer 1

Answer:

16/25

Step-by-step explanation:

We just have to find the probability that the 8 non-defects are chosen.

1. Chance first defect is undetected: 8/10 = 4/5

2. Chance second defect is undetected: 4/5

3. Total probability': 4/5 * 4/5 = 16/25
