Last option.

Step-by-step explanation:

For this exercise you need to find the Discriminant.

The formula used to find the Discriminant, is the following:

D=b^2-4ac

In this case, given the Quadratic equation:

6x^2-2x+7=0

You can identify that:

$a=6\\b=-2\\c=7$

Knowing those values, you must substitute them into the formula and then you must evaluate in order to find the Discriminant.

You get that this is:

$D=(-2)^2-4(6)(7)\\\\D=-164$

By definition, if:

Then the Quadraitc equation has 2 nonreal solutions.

Option C. $\frac{5}{8}$ is the correct option.

Step-by-step explanation:

In the given question numbers marked on a spinner are given = 8

Out of these numbers marked on spinner number of vowels are = 3

Therefore the sample set n(S) is = 8

and the favorable events are n(E) = 3.

As per rules of the probability, the probability of spinning the spinner and landing on vowel will be = $\frac{n(E)}{n(S)}=\frac{3}{8}$

Now probability of spinning the spinner and not landing on a vowel will be

P(E)' = $1-\frac{3}{8}=\frac{5}{8}$

Option C. $\frac{5}{8}$ is the answer.
