Answer:
![P(Pink) = \frac{1}{4}](https://tex.z-dn.net/?f=P%28Pink%29%20%3D%20%5Cfrac%7B1%7D%7B4%7D)
![P(Both\ Black) = \frac{9}{16}](https://tex.z-dn.net/?f=P%28Both%5C%20Black%29%20%20%3D%20%5Cfrac%7B9%7D%7B16%7D)
--- Two pink and One black
Step-by-step explanation:
Represent the pink skin with P and the black skin with B.
Since black skin is dominant to pink skin, there will be more occurrence of B than P
The punnet square for the breeding of the two pigs is then represented as:
![\begin{array}{cc} {B} & {B} \ \\ {B} & {P} \ \ \end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bcc%7D%20%7BB%7D%20%26%20%7BB%7D%20%5C%20%5C%5C%20%7BB%7D%20%26%20%7BP%7D%20%5C%20%5C%20%5Cend%7Barray%7D)
Solving (a): Probability of Pink
In the above square, there is only 1 occurrence of P out of a possible of 4.
So, the probability is:
![P(Pink) = \frac{n(P)}{4}](https://tex.z-dn.net/?f=P%28Pink%29%20%3D%20%5Cfrac%7Bn%28P%29%7D%7B4%7D)
![P(Pink) = \frac{1}{4}](https://tex.z-dn.net/?f=P%28Pink%29%20%3D%20%5Cfrac%7B1%7D%7B4%7D)
Solving (b): Probability that first and second are black
In the above square, there is only 3 occurrence of B out of a possible of 4.
![P(Black) = \frac{n(B)}{4}](https://tex.z-dn.net/?f=P%28Black%29%20%3D%20%5Cfrac%7Bn%28B%29%7D%7B4%7D)
![P(Black) = \frac{3}{4}](https://tex.z-dn.net/?f=P%28Black%29%20%3D%20%5Cfrac%7B3%7D%7B4%7D)
So, the probability that both are black is:
![P(Both\ Black) = P(Black) * P(Black)](https://tex.z-dn.net/?f=P%28Both%5C%20Black%29%20%3D%20P%28Black%29%20%2A%20P%28Black%29)
![P(Both\ Black) = \frac{3}{4} * \frac{3}{4}](https://tex.z-dn.net/?f=P%28Both%5C%20Black%29%20%20%3D%20%5Cfrac%7B3%7D%7B4%7D%20%2A%20%5Cfrac%7B3%7D%7B4%7D)
![P(Both\ Black) = \frac{9}{16}](https://tex.z-dn.net/?f=P%28Both%5C%20Black%29%20%20%3D%20%5Cfrac%7B9%7D%7B16%7D)
Solving (c): Probability of two pink and 1 black
This is calculated as:
![Probability = P(Pink) * P(Pink) * P(Black)](https://tex.z-dn.net/?f=Probability%20%3D%20P%28Pink%29%20%2A%20P%28Pink%29%20%2A%20P%28Black%29)
![Probability = \frac{1}{4} * \frac{1}{4} * \frac{3}{4}](https://tex.z-dn.net/?f=Probability%20%3D%20%5Cfrac%7B1%7D%7B4%7D%20%2A%20%5Cfrac%7B1%7D%7B4%7D%20%2A%20%5Cfrac%7B3%7D%7B4%7D)
![Probability = \frac{3}{64}](https://tex.z-dn.net/?f=Probability%20%3D%20%5Cfrac%7B3%7D%7B64%7D)

Im just gunna go ahead and send all the answers bro
For the Store with sales of 500 in first month just put (The sale for first month is $500.
The sale increases by $10 each month, as modelled by the equation: a_k=500+(k-1)10 = 131,400$)
The last one just copy and paste --> Distribute 2j to (j+3). Rewrite the summation as the sum of two individual summations. Evaluate each summation using properties or formulas from the lesson. The lower index is 1, so any properties can be used. The sum is 5,494,000.

Two things to remember:
a. the slope is the rise/run
b. if it is goin from up to down as you look from left to right of the graph then it is a negative slope
So this one is going up three, over 1
so
3/1 which is the same thing as just 3
since the slope is going down from left to right
it is -3
The slope is -3
Hope this helps :)
