Essay

Provide an appropriate response.
-Identify each of the variables in the Binomial Probability Formula.
$\mathrm{P}(\mathrm{x})=\frac{\mathrm{n} !}{(\mathrm{n}-\mathrm{x}) ! \mathrm{x} !} \cdot \mathrm{p}^{\mathrm{x}} \cdot \mathrm{q}^{\mathrm{n}-\mathrm{x}}$
Also, explain what the fraction $\frac{n !}{(n-x) ! x !}$ computes.
