Using the binomial distribution, it is found that they would expect to find 240 dead batteries among the entire 12,000.
For each battery, there are only two possible outcomes, either it was dead or it was not. The probability of a battery being dead is independent of any other battery, hence the binomial distribution is used to solve this question.
<h3>What is the binomial probability distribution?</h3>
It is the <u>probability of exactly 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
In this problem, we have that:
- One in 50 batteries are dead, hence p = 1/50 = 0.02.
- There is a total of 12,000 batteries, hence n = 12000.
Then:
E(X) = np = 12000(0.2) = 240
They would expect to find 240 dead batteries among the entire 12,000.

The answer is the 3rd option
The third diagram is the correct answer.
We know that
An acute triangle is a triangle with all three angles acute (less than 90 degree ).
An obtuse triangle is one with one obtuse angle (greater than 90 degree) and two acute angles.
A right triangle is one with one right angle (angle equal to 90 degree ) and two acute angles.
therefore
The answer is
Is not possible
Anything greater than (1/5) that is positive
Ex. (1/4), (1/3), (1/2), 1, 2, 3, 4, 5
