A binomial probability experiment is conducted with given parameters. Compute the probability of x successes in the n independen
snow_lady [41]

Answer:

P(X = 4) = 0.1876

Step-by-step explanation:

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

In this question:

n = 15, p = 0.2

We want P(X = 4). So

P(X = 4) = C_{15,4}.(0.2)^{4}.(0.8)^{11} = 0.1876

Keep gettin those wrong. Please help!!!

Answer: About 14.14 in^3

Step-by-step explanation:

We know that the circumference of a sphere is C=2πr. We are given that the circumference is 9.42 in. We can find the radius to get our volume.

9.42=2\pi r

4.71=\pi r

r=1.5\\

Now that we know radius, we can find our volume.

V=\frac{4}{3} \pi r^3

V=\frac{4}{3} \pi (1.5)^3

V=14.14in^3
