Step-by-step explanation:
<u>Probabilities</u>
When we choose from two different sets to form a new set of n elements, we use the so-called hypergeometric distribution. We'll use an easier and more simple approach by the use of logic.
We have 6 republicans and 4 democrats applying for two positions. Let's call R to a republican member and D to a democrat member. There are three possibilities to choose two people from the two sets: DD, DR, RR. Both republicans, both democrats and one of each. We are asked to compute the probability of both being from the same party, i.e. the probability is

Let's compute P(DD). Both democrats come from the 4 members available and it can be done in
different ways.
For P(RR) we proceed in a similar way to get
different ways.
The total ways to select both from the same party is

The selection can be done from the whole set of candidates in
different ways, so


B would equal logx (-2x^5/a)-2
A would equal -2x^3-b (The b is up there with the 3 as well. Like ^3-b)
Diameter = 2r
6 = 2r r = 3 for the radius of the flowerbed
If we were to include the sidewalk around the bed, the diameter would stretch out another meter in both directions, meaning adding 2 meters to the diameter making the new diameter 6 + 2 = 8 and 8/2 = 4 so 4 = radius of the circle including the sidewalk. Find the area of the big circle and subtract the area of the smaller circle to find the area of the sidewalk.
Small circle = pi*3 squared.
