Question

There is a bag of tiles where 8 are red, 5 are blue, 4 are orange, and 3 are green. If one is picked at random, replaced, and another marble is picked, what is the probability that they are both orange? in a percent or fraction

Answer 1

There would be 1/25 chance (4%).

Explanation:

So there's 4 orange marbles and there's 20 total marbles since:

8 Red + 5 Blue + 4 Orange + 3 Green

With this, the chance of drawing an orange marble is 4/20, or 1/5. Because the marble is replaced back after being picked, the same chance would occur for the second picking.

To combine these chances, multiply them together for the answer.

1/5 * 1/5 = 1/25 (4%)

Answer 2

8+5+4+3=20
(1/20)*(1/20)=1/40
