Step-by-step explanation:

Given, a circle with radius, $r=4 \ cm$

Area of circle = $\pi r^2$

Substitute $r=4$

Area of whole circle $=\pi r^2\\=\pi\times 4^2\\=16\pi \\=50.2654\ cm^2$

Square is inscribed in it whose each side is $4\sqrt{2}\ cm$

Area of square $=side^2\\=(4\sqrt{2} )^2\\=16\times 2\\=32 \ cm^2$

We can see that area of the white circle

= area of the whole circle - area of square

$=50.2654-32\\=18.2654 \ cm^2$

Probability of falling a random point within the white circle

$=\frac{area\ of\ white\ circle}{area\ of\ whole\ circle}$

$=\frac{18.2654}{50.2654} \\=0.3633$

Rounding to nearest hundredth.

Probability of falling a random point within the white circle would be 0.36

Answer:

$P(X=7)$

And using the probability mass function we got:

$P(X=7)=(15C7)(0.23)^7 (1-0.23)^{15-7}=0.0271$

Step-by-step explanation:

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

$X \sim Binom(n=15, p=0.23)$

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 want to find the following probability:

$P(X=7)$

And using the probability mass function we got:

$P(X=7)=(15C7)(0.23)^7 (1-0.23)^{15-7}=0.0271$
