<h3>
Answer: 1/3</h3>
===================================================
Explanation:
A = multiples of 5 between 1 and 30
A = {5,10,15,20,25,30}
B = multiples of 6 between 1 and 30
B = {6,12,18,24,30}
There are 6 items in set A and 5 items in set B. This gives 6+5 = 11 items overall; however, notice that "30" shows up twice. So we have to subtract off 1 to account for this. This means there are 11-1 = 10 unique values that are either a multiple of 5, a multiple of 6, or a multiple of both. This is out of 30 numbers in the set {1, 2, 3, ... , 29, 30}
The probability we want is 10/30 = 1/3

I’m confused on what to do I’m not sure
Given that the population quadruples every 39 minutes, you can determine that this bacteria population has Exponential Growth.
By definition, an Exponential Equation as this form:

Where "a" is the initial amount, "b" is the base, and "t" is the time period.
In this case, you know that:

Therefore, since you need to express the time "t" in minutes:

Now you can write the following equation to model the situation:
