Click on the green button below. The total
for the roll is a favorable outcome for the number rolled. Rolling dice produces data for
experimental probability.

There are 36 possible outcomes each time two dice are
thrown. Study the pattern of the animation below.

Virtual dice for generating experimental and theoretical probability data.

Experiment: Toss the dice 100 times. If 12 comes up 10 times,
what is the experimental probability.

The theoretical probability of the event is the fraction:

# ways the event can occur

total possible outcomes

The experimental probability for equally likely events is the fraction:

# favourable outcomes

total outcomes

Look at the chart above. The theoretical
probability of the event that 12 comes up is:

P(12) = 1/36 = 0.028 = 2.8%

If in this experiment, 12 is rolled 3 times,
the experimental probability of the event that twelves comes up is:

P(12) = 3/100 = 0.03 = 3%

Other sites show the theoretical probability and or
experimental probability of rolling particular numbers when two dice are rolled.

Choose to roll one die or two dice. Click on an arrow beside the run
button to increase or decrease the number of trials. The help button that has
a more detailed explanation of how to use this applet.
