I think b would be the correct answe

Hello, Shakiya214!
If a fish tank contains 16 goldfish and 24 guppies, then we can deduce that the total number of fish in the tank is: 16 + 24 = 40 fish.
If there are 16 goldfish in the tank, then of the 40 total fish, we have a probability of 16/40.
To illustrate this idea, suppose we had n fish in the tank (a guppies and b goldfish). The probability of selecting any fish is 100% (because there are only fish in the tank). If we had to select the goldfish, we could choose them like this:
p₁, p₂, p₃, p₄ ... pₐ
We could choose any one of these fish twice. This leaves us with: 16/40
Now, if they were NOT replaced, we could simply do it again. Except this time, we can only choose 15 out of the remaining 39 goldfish, leaving us with a probability of: (16/40)(15/39) = 240/1560 = 6/39 = 2/13
Answer:
I believe the whole number will be 1 because 3+1 is 4 and 4/4 is one. then you just drop the 4/5. so the equation may be 1 - 4/5
First get all the terms on the same side:

Now solve using the quadratic formula which is:

Plug in the values:

So the answer is:
The y intercept will be 0
