the probability of passing an examination is 0.8 what is the probability of failing the examination

Show me the solving of the question

How did you get the answer

The probability of passing an examination is 0.8, what is the probability of failing the examination

To find the probability of failing the examination, we can subtract the probability of passing from 1. Since the probability of passing is 0.8, the probability of failing can be calculated as follows:

Probability of failing = 1 - Probability of passing

Probability of failing = 1 - 0.8

Probability of failing = 0.2

Thus, the probability of failing the examination is 0.2, or 20%.

0.2
