The probability of randomly selecting a switch that is not defective is 88%
How to determine the probability?
The given parameters are:
- Number of switch = 25
- Number of defective switch = 3
The number of switch that are not defective is calculated using:
Not defective = 25 - 3
Evaluate
Not defective = 22
The probability is then calculated as:
P(Not defective) = 22/25
Express as percentage
P(Not defective) = 88%
Hence, the probability of randomly selecting a switch that is not defective is 88%
