entalprobability.php Students learn that
probability can be found by conducting an
experiment. For example, given a number cube
that has the numbers 1, 2, 3, 4, 5, and 6 on
its faces, students are asked to toss the
number cube 6 times and use the results to
determine the probability of rolling a given
number, such as 4. Note that the theoretical
probability of rolling a 4 is 1/6 (1
favorable outcome) / (6 possible outcomes),
but the experimental probability may be
different from 1/6. For example, if a student
tosses the number cube 6 times and fails to
toss a 4, the experimental probability will
be 0/6, or 0. Students learn that
experimental probability approaches
theoretical probability as the number of
trials increases. For example, if a student
tosses the number cube 100 times, the
experimental probability of rolling a 4 will
approach 1/6.
