<u><em>Part 1:</em></u><u>Before we begin, you need to remember the following rule:</u>

<u>The given expression is:</u>

Since the base is the same in both numerator and denominator, we can apply the above rule. <u>This means that:</u>

= 12¹⁻³ = 12⁻²
<u><em>Part 2:</em></u><u>Before we begin, you need to remember the following rule:</u>
x⁻ᵃ =

Now, <u>from part 1</u>, we simplified the expression into 12⁻²
Since the power is negative, we can apply the above rule.
<u>This means that:</u>
12⁻² =

Hope this helps :)

Answer:
The probability of the number of Protestants that were calm for 2 out of 3 days is 0.061.
Step-by-step explanation:
Represent the provided data as follows:
Compute the probability of the number of Protestants that were calm for 2 out of 3 days as follows:

The number of Protestants surveyed is, <em>n</em> (Protestants) = 99.
The number of Protestants who were calm for 2 days,
<em>n</em> (Protestants who were calm for 2 days) = 6
The required probability is:

Thus, the probability of the number of Protestants that were calm for 2 out of 3 days is 0.061.
