Total number of Student in the School in which half are boys and Half are girls =20
Probability of an event
\(=\frac{\text{Total favorable oucome}}{\text{Total Possible outcome}}\)
Probability of Number of Boys as well as Probability of Number of Girls
\(=\frac{10}{20}\\\\=\frac{1}{2}\)
The Most appropriate option is
Option C
Count how many boys and girls are in your math class and use a proportion.
In Option A, B and D
The probability of each outcome that is Success and Failure will be nearly equal to 0.50 .
But in Option C, you can't say precisely that Probability will be equal to , 0.50 in each case , that is Success and Failure.
