Quantitative Methods Q159

159A company has two bottle producing machines, one old and one new. The older machine produces 10% defective bottles, whereas the new machine produces 4% defective bottles only. Additionally, the new machine uses latest technology to produce 5 times as many bottles as the older machine. Given that the bottle was produced by the new machine, what is the probability that it is not defective?

Option : B
Explanation : The question is asking for the probability of a bottle produced by the new machine which is not defective. In the question, the probability of defective is given as 4% and therefore, the probability of not defective will be 1 - 0.04 = 0.96.
