Neco Model Questions Vol1 2019 Mathematics Question 19
Practice objective / multiple choice question 19 from the 2019 Neco Model Questions Vol1 Mathematics examination.
In a factory, two types of widgets are produced: type A and type B. The proportion of type A widgets is \(p\) and type B is \(1-p\). The probability that a type A widget is defective is \(0.02\) and that a type B widget is defective is \(0.05\). A widget selected at random is found to be non‑defective. Given that the probability the selected widget is of type A, conditional on it being non‑defective, is \(0.8\), determine the value of \(p\). Express your answer as a reduced fraction.
