X^2 + 2 = x + 8
x^2 - x + 2 - 8 = 0
x^2 - x - 6 = 0
Input 1 => 1^2 - 1 - 6 = 1 - 1 - 6 = -6
Input 3 => 3^2 - 3 - 6 = 9 - 3 - 6 = 0
Input 4 => 4^2 - 4 - 6 = 16 - 4 - 6 = 6
Input 5 => 5^2 - 5 - 6 = 25 - 5 - 6 = 14
Solution set { -6, 0, 6, 14}
Answer:
There is a 44.16% probability that exactly 1 of the tested bottles is contaminated.
Step-by-step explanation:
is the number of different combinatios of x objects from a set of n elements, given by the following formula.

In this problem, we have that:
Total number of combinations:

Desired combinations:
It is 1 one 5(contamined) and 2 of 17(non contamined). So:

What is the probability that exactly 1 of the tested bottles is contaminated?

There is a 44.16% probability that exactly 1 of the tested bottles is contaminated.
