In a classical study it is observed that out of 6115 families with 12 children, 38100 of the 73380 children in total are boys. How many families with exactly 6 boys can be expected if the binomial distribution is used to describe the number of boys out of 12 children in a family.

$6115\cdot 0.519^6(1-0.519)^6$

$73380\cdot \left(\begin{array}{c}12 \ 6\end{array}\right) 0.519^6(1-0.519)^6$

$\left(\begin{array}{c}12 \ 6\end{array}\right) 0.519^6(1-0.519)^6$

$6115\cdot \left(\begin{array}{c}12 \ 6\end{array}\right) 0.519^6(1-0.519)^6$

$6115\cdot \left(\begin{array}{c}12 \ 6\end{array}\right) 0.5^6(1-0.5)^6$
