The solution in the post by @MathLover1 is incorrect.
She incorrectly determined frequencies for B, C and F in her post.
The correct frequency for B is 8 (instead of 6 in the post by @MathLover1).
The correct frequency for C is 7 (instead of 5 in the post by @MathLover1).
The correct frequency for F is 2 (instead of 1 in the post by @MathLover1).
So, the numbers in her Table are incorrect;
her pie-chart is incorrect and the numbers in her pie-chart are incorrect, too.
To make a pie chart, use one of many free of charge sites in the Internet,
for example, these
