You carry out an experiment and record the results. You then can use these results to calculate the experimental probabilities.

If you roll a die 30 times and get

3 ones
3 twos
1 threes
10 fours
3 fives
6 sixes

The theoretical probability of rolling a number is #1/6# so you would say that you might expect 5 ones in 30 rolls. The experimental probability is

Ones #3/30=1/10#

Twos #3/30=1/10#

Threes #1/30#

Fours #10/30=1/3#

Fives #3/30=1/10#

Sixes #6/30=1/5#
