Answer:
The probability is 0.357
Step-by-step explanation:
Given that,
The system has at least one type of defect,
Suppose, A certain system can experience three different types of defects.
Let (i = 1,2,3) denote the event that the system has a defect of type i.
Suppose that the following probabilities are,
We need to calculate the probability that it has exactly one type of defect
Using given data
+ +
P =
Put the value into the formula
Hence, The probability is 0.357
