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 $\frac{1}{6}$ $1/6$ so you would say that you might expect 5 ones in 30 rolls. The experimental probability is

Ones $\frac{3}{30} = \frac{1}{10}$ $3/30=1/10$

Twos $\frac{3}{30} = \frac{1}{10}$ $3/30=1/10$

Threes $\frac{1}{30}$ $1/30$

Fours $\frac{10}{30} = \frac{1}{3}$ $10/30=1/3$

Fives $\frac{3}{30} = \frac{1}{10}$ $3/30=1/10$

Sixes $\frac{6}{30} = \frac{1}{5}$ $6/30=1/5$
