To start, we need the total number of marbles, which is 14 + 9 = 23
Since there are 14 shaded marbles, the probability of taking a shaded marble out of a bag would be 14/23, which is about 0.607.
There are also 9 unshaded marbles, so the probability of taking an unshaded marble would be 9/23, which is 0.391.
(You can also find that by just subtracting 1 - 0.607.)
