and
, we need to clear
and eliminate it afterwards to obtain a function of the form
:


(1)


(2)
By (1) and (2):



Hence, the correct answer is C.
First, you need to choose a yellow marble. That is 6/15.
Next, you need to choose a blue marble. That is 5/14, because 1 yellow marble would have been "chosen" already.

because there are one woman and one man
It will take Lauren 1.25 seconds to hit the water.
With the given information, we can write the following quadratic equation.

Now, just use the quadratic formula to solve the equation.
You will get 1.25 and -0.75 as the zeros of the equation (where Laruen hits the water).
Only 1.25 makes sense in the context of this problem.
