Note for probability, if it will never happen the P = 0. If it must happen P = 1.

So certain to happen:

C. P=1

8 0

The probability of the occurrence of an event ranges only from 0 to 1. Thus, eliminating the fourth choice, P = 100. If an event is not bound to happen, P = 0. If there are circumstances that may hinder it to happen, the probability is somewhere between the extremes. Lastly, if it certain to happen, the probability is 1. Therefore, the answer is letter C.

Answer:

Step-by-step explanation:

First, simplify sqrt(18/30) into sqrt(3/5). This equals (sqrt(3))/(sqrt(5)) or (sqrt(15))/5. Now, multiply it by 8 to get $\boxed{8\sqrt{15}\over5}$ or D.
