Answer: 1/10

Explanation: 3/9 times 3/10 equals 9/90, simplify and you'll get 1/10

There are 3 red, that is where the first numerator comes from and there are 10 marbles so that is where the denominator comes from. There are 3 yellows, hence the second numerator but as we have taken a marble out there are now only 9 marbles in total.
