Question

You flip a coin 20 times and get tails 9 times. Based on this experiment, what is the probability of flipping a coin and getting tails?

Answer 1

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
