Given

The number of times the coin was flipped = 20 times

The number of times tails showed up = 9 times

Mathematically, the formula for the experimental probability is defined by:


Probability\text{ of an event P\lparen E\rparen = }\frac{Number\text{ of times an event occurs}}{Total\text{ number of trials}}

Based on the experiment, the probability of flipping a coin and getting tails can be found using the formula above.

Applying the formula:


P(flipping\text{ a coin and getting tails\rparen = }(9)/(20)

Answer: 9/20
