Therefore the experimental probability of the coin landing on tails can be calculated by the dividing the times it landed on tails by the total number of times it was tossed. Like so...

\frac{33}{75} or 0.44

This fraction can also be simplified to its simplest form of \frac{11}{25} which is obtained by dividing both the numerator and denominator by 3
