3. 9 to 45 ---> b. 7 to 35
(9/45 and 7/35, both have the same answer(ratio) which is equal to 1/5)
4. 2 to 20 ---> a. 1 to 10
(2/20 and 1/10, both have the same answer(ratio) which is equal to 1/10)
5. 4 to 12 ---> d. 10 to 30
(4/12 and 10/30, both have the same answer(ratio) which is equal to 1/3)
The type and number of solutions is (b) two imaginary solutions.
<h3>How to determine the type and number of solutions?</h3>
The equation is given as:
3x² + 5x + 5 = 0
A quadratic equation can be represented as:
ax^2 + bx + c = 0
Where, the discriminant (d) is
d = b^2 - 4ac
So, we have
d = 5^2 - 4 * 3 * 5
Evaluate
d = -35
The value of d is negative
This means that the equation has only imaginary solutions
Hence, the type and number of solutions is (b) two imaginary solutions.

The answer is C. 75. Hope this helps.
There were 5 of the 15 in the simulation that used a coupon. To find the probability you just divide 5 by 15
P(=>4) = 5/15 = 1/3 - probability of 4 or more
