Neco 2022 Mathematics Question 10
Practice objective / multiple choice question 10 from the 2022 Neco Mathematics examination.
A bag contains red, blue and green balls. The probability of drawing a red ball is twice that of drawing a blue ball, and the probability of drawing a green ball is 0.1. A ball is drawn at random, its colour noted, and then the ball is returned to the bag. The experiment is repeated independently a total of five times. Given that exactly two of the five draws resulted in a red ball, what is the probability that exactly one of the remaining three draws was blue? Express your answer as a fraction in lowest terms.
