Neco 2022 Civic Education Question 21
Practice objective / multiple choice question 21 from the 2022 Neco Civic Education examination.
A government agency monitors 120 contracts. Historically 8% involve corruption. After a new anti‑corruption policy, the probability that a corrupt contract is detected rises to 0.75, while a non‑corrupt contract is falsely flagged with probability 0.05. In a random audit of 10 contracts, what is the probability that exactly 2 contracts are flagged as corrupt? Use the binomial formula \(P = \binom{10}{2} p^{2} (1-p)^{8}\). Express your answer as a decimal rounded to three places.
