Hi there! Let's say I have 2 green marbles, 2 blue marbles, and 2 black marbles. You would add 2+2+2 which equals 6. Now, what is the probability that the marble will be blue? Well that's easy because the denominator would be 6 and the numerator would be 2. So, we have a fraction of 2/6. 26 simplified is 1/3. Therefore, the probability would be 1/3.
