These are the events in the question above:
<span>D - has disease
</span>
<span>H - healthy (does not have disease)
</span>
<span>P - tests positive </span>
<span>It is the probability that a person has the disease AND tests positive divided by the probability that the person tests positive.
</span>
Sick, + [.04*.91] = .0364
<span>Sick, - [.04*.09] = .0036 </span>
Healthy, + [.96*.04] = 0.0384
<span>Healthy, - [.96*.96] = .9216
</span>
.0364 / (.0364 + .0.0384) = 0.487
Yes, in the sense that the new area could be written as (x+1)^2 / 1.
Usually we would not bother with the "1" as divisor.
Let's actually do the work: what is the area of the square if we increase the side length of the existing square by 1 ft?
(x+1)^2 = x^2 + 2x + 1 (This is not a fraction, and thus not the ratio of
two integers, which, in turn, is the definition of
"rational number."
