How do you simplify a fraction?

Back

To simplify a fraction, divide the numerator and the denominator by their greatest common divisor (GCD).

Front

What is the probability of picking an Orange and Yellow M & M from the bag?

Back

Probability = (Number of Orange M & M's * Number of Yellow M & M's) / (Total M & M's)^2 = (3 * 2) / (21^2) = 6/441 = 2/147.

Front

What is the probability of picking a Green and Blue M & M from the bag?

Back

Probability = (Number of Green M & M's * Number of Blue M & M's) / (Total M & M's)^2 = (5 * 4) / (21^2) = 20/441.
