A bag holds the following marbles:

6 blue

5 gold

4 white

3 orange

2 clear

Andrew is hoping to get either a clear one or a white one, since he doesn't have those colors yet. What are the chances that the next marble he picks at random will be either clear or white?

total marbles = 20

chances for clear are 2/20 which reduces to 1/10
chances for white are 4/20 which reduces to 2/5

1/10 * 2/5 = 2/50 which reduces to 1/25 (chances of choosing clear or white)
