Answer:
a. .0125
Step-by-step explanation:
For each part, there are only two possible outcomes. Either it is defective, or it is not. The probability of a part being defective is independent of any other part. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
2% defective parts.
This means that
A sample of nine parts from the production process is selected.
This means that
What is the probability that the sample contains exactly two defective parts?
This is P(X = 2).
0.0125 = 1.25% probability that the sample contains exactly two defective parts. The correct answer is given by option a.
