Question

A bottle contains 3 red marbles, 5 blue marbles and 2 green marbles. If a single marble is drawn from the bottle at random, what is the probability that the marble is green?

Answer 1

1/5

Explanation:

There are 3+5+2 = 10 marbles in the bottle

P(green) = number of green marbles/ total

= 2/ 10 = 1/5
