Binomial Probability Distribution. How to determine the probability of one candidate of two winning.

1 answer:

4 0

.5

B - binary?
I - independent?
N - trials
S - prob success

B - yes, win or not
I - past candidates don’t affect future candidates
N - 2 candidates
S - .5 probability of winning

Go to the binompdf function on your graphing calculator.

binompdf(2 (trials), .5 (p), 1 (1)) = .5

$\frac{x^2-25}{x^2-2x}\times \frac{x-2}{x^2+5x}$

Let's factor all four of these before we multiply.

x² - 25
We want two numbers that add to -25 and multiply to 0.
= (x+5)(x-5)

x² - 2x
Both terms are divisible by x.
= x(x-2)

x - 2
unfactorable

x² + 5x
Both terms are divisible by x.
= x(x+5)

Now we have this:

$\frac{(x+5)(x-5)}{x(x-2)}\times \frac{x-2}{x(x+5)}$

Let's go ahead and multiply across.

$\frac{(x+5)(x-5)(x-2)}{x(x-2)x(x+5)}$

Cancel out the (x+5) and (x-2) from the top and the bottom.

$\boxed{\frac{x-5}{x^2}}$
