Write the probability of drawing the asked colour as a fraction.
There are 0 marbles in the bag. What is the probability that a randomly drawn marble is red?
What does the generator do?
The generator fills a bag with 3 to 10 marbles in 2 or 3 colours and asks for the probability of drawing one specific colour. The answer is always a fraction; any equivalent form (e.g. 2/4 = 1/2) is accepted.
How to solve
Count how many marbles match the asked colour — that is the numerator. Count all marbles — that is the denominator. Write the fraction and, if it can be simplified, do that too.
