Answer:

$P(X=0)=(2C0)(0.84)^0 (1-0.84)^{2-0}=0.0256$

And replacing we got:

$P(X \geq 1)=1 -P(X$

Step-by-step explanation:

Let X the random variable of interest, on this case we now that:

$X \sim Binom(n=2, p=1-0.16=0.84)$

The probability mass function for the Binomial distribution is given as:

$P(X)=(nCx)(p)^x (1-p)^{n-x}$

Where (nCx) means combinatory and it's given by this formula:

$nCx=\frac{n!}{(n-x)! x!}$

And we can find this probability:

$P(X \geq 1)$

And we can solve this probability like this:

$P(X \geq 1)=1 -P(X$

And if we use the probability mass function we got:

$P(X=0)=(2C0)(0.84)^0 (1-0.84)^{2-0}=0.0256$

And replacing we got:

$P(X \geq 1)=1 -P(X$

The shaded area = the arced area - the area of the triangle

The arced area = (120/360) * pi * 6^2 = 12pi

The height of the triangle is 6*sin60 = 3√3

So the area of the triangle is 1/2 * 6 * 3√3 = 9√3

So the shaded area = 12pi - 9√3
