Front

What is the total number of outcomes when rolling two dice?

Back

36 outcomes (6 sides on the first die x 6 sides on the second die).

Front

What is the formula for calculating probability?

Back

P(Event) = Number of favorable outcomes / Total number of outcomes.

Front

If a box contains 10 blue marbles and 5 yellow marbles, what is the probability of drawing a yellow marble?

Back
