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\%
