Step-by-step explanation:

We know the area of a circle is

$\pi {r}^{2}$

That is when the cricle is 360 degrees full, so another formula is

$\frac{360}{360} \pi {r}^{2}$

If we the find the area of the sector with angle x, then that formula will be

$\frac{x}{360} {\pi}r^{2}$

F(x,n,p)=C(n,x)p^x*(1-p)^(n-x)
n=9, p=0.8 =>
f(x,9,0.8)=C(9,x)0.8^x*(0.2)^(9-x)

The function f(x,9,0.8) is then calculated using the above formula
