Question

There is a bag filled with 4 blue, 3 red and 5 green marbles. A marble is taken at random from the bag, the colour is noted and then it is not replaced. Another marble is taken at random. What is the probability of getting 2 reds?

Answer 1

Explanation:

4+3+5= 12 marbles

3/12 * 2/11 = 6/132 = 4.5%
