Answer:
5/28
Step-by-step explanation:
First of all, probability is defined as the number of ways a certain event can happen divided by the total ways of an event happening. In this scenario, we are asked to find the number of non-defective computers divided by the total ways that a sample of two can be chosen.
The number of ways to choose 2 computers from 8 can be written as , which is equal to
, which is 28. Now, there are 3 defective computers, for a total of 5 non-defective computers, so the probability is 5/28.
