In theoretical probability you don't consider what previously happened in the experiment (that is the experimental probability that takes into an account the experiment made)

3. SolomonZelman

(Number of favorable outcomes) ÷ (Number of all possible outcomes)

4. anonymous

is it 1/8?

5. SolomonZelman

yup sir!

The probability that an event will occur is 1. Which of the following best describes the likelihood of the event occurring? Likely Certain Unlikely Impossible

7. ikram002p

can it happen ?

8. anonymous

i think certain

9. SolomonZelman

when theoretical probability is 1, favorable outcomes / all possible outcomes =1 thus, favorable outcomes = all possible outcomes

10. SolomonZelman

hence all possible outcomes are favorable, saying that every outcome (saying, no matter how it comes out) , it will then come out in a desired way. that is, the answer is certain. Correct!

At a school carnival, the diameter of the mat of a trampoline is 10 feet and the diameter of its metal frame is 12 feet. What is the length, in feet, of the metal frame that surrounds the trampoline? Use 3.14 for π and round your answer to the nearest tenth. 15.7 feet 18.9 feet 31.4 feet 37.7 feet

12. SolomonZelman

Ok, you want the length of the frame or the area of the frame? For the length of the frame, it is: $$\large \displaystyle L=\pi D=(3.14)\cdot (12)=~...$$

13. SolomonZelman

I mean this L (length) is really the C (circumference).
