Question

A product has a 12% chance of being defective. If you randomly select 50 of the product, what is the probability that exactly 6 of them are defective? Round your answer to two decimal places.

Answer 1

Solution :

Given that ,

Using binomial probability formula ,

P(X = x) = (_n C _x) * p^x * (1 - p)^{n - x}

P(X = 6) = (₅₀ C ₆) * 0.12⁶ * (0.88)⁴⁴

= 0.1712

Probability = 0.1712
