A bag contains 20 marbles that are red, blue, yellow or green.
There are 3 yellow marbles and 9 red marbles.
The probability I pick a blue marble is the same as a green marble.
What is the probability I pick a green marble as a fraction?
3 + 9 = 12
20 - 12 = 8 marbles left (blue or green)
Probability of blue and green is the same so 8 ÷ 2 = 4 marbles each
So the probability I pick a green marble is
4/20
