Option 4:
Step-by-step explanation:
A rational expression is undefined if the denominator (The bottom part of the fraction) is zero. If the denominator is zero, the fraction is automatically considered undefined, since there will never be an answer to the fraction.
To solve this question, all we need to do is replace x with 0 in the denominator, and see whether it becomes 0 or not.
For the steps I'll be writing below, I'll only be solving for the denominator since the value of the numerator does not matter at all in this question.
1. 3x - 3 --> 3(0) - 3 --> -3. The denominator is not zero, so it is defined.
2. 9x - 3 --> 9(0) - 3 --> -3. The denominator is not zero, so it is defined.
3. -x^2 + 1 --> -(0)^2 + 1 --> 1. The denominator is not zero, so it is defined.
4. -2x^2 --> -2(0)^2 --> 0. The denominator is zero, so it is undefined.
Since the 4th option was the only answer choice where the denominator became 0, that is our final answer.
(4x - 8)/(-2x^2) is undefined.
<u>Answer-</u>
a. Probability that three of the candies are white = 0.29
b. Probability that three are white, 2 are tan, 1 is pink, 1 is yellow, and 2 are green = 0.006
<u>Solution-</u>
There are 19 white candies, out off which we have to choose 3.
The number of ways we can do the same process =
As we have to draw total of 9 candies, after 3 white candies we left with 9-3 = 6, candies. And those 6 candies have to be selected from 52-19 = 33 candies, (as we are drawing candies other than white, so it is subtracted)
And this process can be done in,
So total number of selection = (969)×(1107568) = 1073233392
Drawing 9 candies out of 52 candies,
∴P(3 white candies) =
Total number of ways of selecting 3 whites, 2 are tans, 1 is pink, 1 is yellow, and 2 are greens is,
Total number of selection = 3 whites + 2 are tans + 1 is pink + 1 is yellow + 2 greens = 9 candies out of 52 candies is,
∴ P( 3 whites, 2 are tans, 1 is pink, 1 is yellow, 2 greens) =
