Question

What is the probability of flipping a coin 10 times and getting heads 5 times?Round your answer to the nearest tenth of a percent.A. 24.6%B. 20.5%C. 11.7%D. 3.1%

Answer 1

Answer: A. 24.6%

Step-by-step explanation

The probability of flipping a coin 10 times and getting heads 5 is given as:

`P=\frac{no.\text{ of succes}}{total\text{ outcomes}}`

Therefore, the probability of getting one head in one turn is 1/2. Then:

`P=(10C5)/(2^(10))=0.246`

Multiplying times the percent:

`0.246*100\%=24.6\%`
