Answer:
--- 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:
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:
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.
So, the probability that both are black is:
Solving (c): Probability of two pink and 1 black
This is calculated as:
<span>-x^2 - 4x when x = -3
-(-3)^2 -4(-3)
= - 9 + 12
= 3
answer is </span><span>B. 3 </span>
B. Is correct I think. Hope this helped you
