A machine produces items with defect probability 0.2. If 10 items from this machine are chosen at random, what is the probability that at most one of them is defective?
- 1/e²
- 2/e²
- 3/e²
- none of these
Correct answer: none of these
Solution
The probability of at most one defective item among 10 can be calculated using the binomial distribution formula, which shows that the resulting probability does not match any of the provided options, confirming that 'none of these' is the correct answer.
