Using the binomial distribution, it is found that the mean and the standard deviation of variable x are given as follows:

<h3>What is the binomial probability distribution?</h3>
It is the probability of exactly <u>x successes on n repeated trials, with p probability</u> of a success on each trial.
The expected value of the binomial distribution is:
E(X) = np
The standard deviation of the binomial distribution is:

In this problem, we have that the parameters are given as follows:
n = 4, p = 0.75.
Hence the mean and the standard deviation are given as follows:
- E(X) = np = 4 x 0.75 = 3.

Answer: 15.7659
Explanation: the column the 4 is in is the ten thousandths column. Since the number after it is 8, which is bigger than 5, you round up to make is 15.7659

Answer: $47.06 if you do not round or $47.07 if you are required to round up.
Step-by-step explanation:
$43.99× .07 = 3.0793
$43.99+ $3.07 = $47.06
(If you round up then follow below)
$43.99× .07= 3.0793 (the 9 would cause you to round the 7 up to 8)
$43.99+ $3.08= $47.07
