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)
Answer:
ok put into y=mx+b form
2y=60x+120
y=30x+60
so we know 60 is the y-intercept so he is not correct
if u want more:
-60x+2y-120=0 add 60x
2y-120=60x add 120
2y=60x+120 divide by 2
y=30x+60
Hope this helps plz hit the crown :D
20%
This is because 20 and it's opposite -20 is 40. (20 - -20 = 40). Then 40 is 20% of 200.
