For 100 tosses yielding 7 bottom landings, 18 top landings, and 75 side landings, the experimental probabilities are P(bottom) = 7/100 = 0.07, P(top) = 18/100 = 0.18, and P(side) = 75/100 = 0.75.
Toss a paper cup into the air 100 times. After each toss record whether the cup lands on its bottom, upside down on its top or on its side (See Fig. 7.5). Assign probabilities to the outcomes by using experimental probability.

In an activity of 100 trials, suppose the observed landing frequencies are:
Bottom lands = 7 times
Top lands = 18 times
Side lands = 75 times.
Using the formula:
Experimental Probability = Number of times the event occurred / Total trials
P(bottom) = 7 / 100 = 0.07 (or 7%)
P(top) = 18 / 100 = 0.18 (or 18%)
P(side) = 75 / 100 = 0.75 (or 75%).
The sum of all experimental probabilities is 0.07 + 0.18 + 0.75 = 1.
