Best answer
Given, A box containing 5 red, 8 white and 4 green marbles. So, the total no. of possible outcomes = 17 (5 red + 8 white + 4 green) (i) Let E = Event of getting a red marble Number of favourable outcomes = 5 (as 5 red marbles) Probability, P(E) = Number of favourable outcomes/ Total number of outcomes P(E) = 5/17 (ii) Let E= event of getting a green marble Number of favourable outcomes = 4 (as 4 green marbles) Probability, P(E) = Number of favourable outcomes/ Total number of outcomes P(E) = 4/17 So, ¯ E = Event of getting not a green marble Then we know that, Therefore, the probability that the marble taken out is not green is 13/17.
