If \(20 \%\) of the bolts produced by a machine are defective then the probability that out of 4 bolts chosen at random, less than 2 bolts will be defective, is
- A 0.2048
- B 0.4096
- C 0.8192
- D 0.1024
Answer & Solution
Correct Answer
(C) 0.8192
Step-by-step Solution
Detailed explanation
We have, \(n=4, p=\frac{20}{100}=\frac{1}{5}, q=1-p=1-\frac{1}{5}=\frac{4}{5}\)…
