Probability = (Number of sections of that color) / (Total number of sections on the wheel).

Front

If a bag contains 2 blue marbles, 3 black marbles, and 5 red marbles, what is the total number of marbles?

Back

Total marbles = 2 + 3 + 5 = 10.

Front

What is the probability of picking a blue marble from the bag?

Back

Probability of blue = (Number of blue marbles) / (Total number of marbles) = 2/10 = 1/5.

Front

What is the probability of picking two blue marbles with replacement?

Back

P(blue and blue) = (2/10) * (2/10) = 1/25.
