Answer: A. 24.6%
Explanation
The probability of flipping a coin 10 times and getting heads 5 is given as:
[tex]P=\frac{no.\text{ of succes}}{total\text{ outcomes}}[/tex]Therefore, the probability of getting one head in one turn is 1/2. Then:
[tex]P=\frac{10C5}{2^{10}}=0.246[/tex]Multiplying times the percent:
[tex]0.246\times100\%=24.6\%[/tex]
