Using the binomial distribution, it is found that:
- The mean of X is of 0.72.
- The standard deviation of X is of 0.81.
<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:
For this problem, the parameters are given as follows:
n = 8, p = 0.09.
Hence the mean and the standard deviation are, respectively:
- E(X) = np = 8 x 0.09 = 0.72.

Answer:
Area = 20 square units
Step-by-step explanation:
=> We know that;
Base 1: 3 units
Base 2: 7 units
Height: 4 units
=> Now let's come up with a congruent base first:
= final base
10/2 = final base
5 = final base
=> Finally, Area of the trapezoid:
A = Final Base * Height
A = 5 * 4
A = 20 square units
