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)

solomonzelman · Answer

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

anonymous · Answer

is it 1/8?

solomonzelman · Answer

yup sir!

anonymous · Answer

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

ikram002p · Answer

can it happen ?

anonymous · Answer

i think certain

solomonzelman · Answer

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

solomonzelman · Answer

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

solomonzelman · Answer

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

solomonzelman · Answer

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

anonymous · Answer

i got 37.68 @SolomonZelman
