Answer:
x = -2, x = 2
Step-by-step explanation:
The denominator factors as ...
x^2 -4 = (x -2)(x +2)
The numerator has no factors that cancel either of these, so the function will have vertical asymptotes where the denominator is zero: at x = -2 and x = 2.
<h3>The exact probability that the blue ball is drawn first and the red ball is drawn second is

</h3>
<em><u>Solution:</u></em>
<em><u>The probability of an event is given as:</u></em>

Given that,
There are 12 balls in a bag
One is blue and one is red
Favorable outcome = blue ball is drawn first
Favorable outcome = 1
Therefore,

Now, without replacement, red ball is drawn second
Therefore,
Total possible outcomes = 12 - 1 = 11

<em><u>What is the exact probability that the blue ball is drawn first and the red ball is drawn second?</u></em>

Thus the exact probability that the blue ball is drawn first and the red ball is drawn second is
