Answer:
The first option .
Step-by-step explanation:
To have exactly 2 real and two non real solutions, the degree of the polynomial must be a degree 4. Degree is the highest exponent value in the polynomial and is also the number of solutions to the polynomial. This polynomial ha 2 real+2 non real= 4 solutions and must be . This eliminates the bottom two solutions.
In order to have two real and two non real solutions, the polynomial must factor. If it factors all the way like
This means x=0, 10, -10 are real solutions to the polynomial. It has no non real solutions. This eliminates this answer choice.
Only answer choice 1 meets the requirement.

1.<em> </em>Find the probability of rolling less than a four.
<u>Probability Outcomes</u> = 1, 2, 3, 4, 5, 6
<u>Outcomes lower than four</u> = 1, 2, 3
Then to answer it you need the probability in the form of a fraction.

2. Find the probability of rolling an even prime number.
<u>Probability Outcomes</u> = 1, 2, 3, 4, 5, 6
<u>Prime Numbers Through 1-6</u> = 2, 3, 5
<u>Even Prime numbers Through 1-6</u> = 2
So the probability in the form of a fraction.
<h3>3. Find the probability of rolling factors of 20.
<u>Probability Outcomes</u> = 1, 2, 3, 4, 5, 6
<u>Factors of 20 Through 1-6</u> = 1, 2, 4, 5
So probabilty in the form of a fraction.
