Log(2x*12)=3
10^3=2x*12
1000=24x
1000/24=x
x=41.667
5 is a prime factor of 155. Dividing 155 by 5, we get 31. 1*5*31 = 155.
Answer:

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?
