You should multiply the experimental probability by the total number of trials in an actual experiment when making a prediction.
<h3>What is an
experimental probability?</h3>
An experimental probability is also referred to as relative frequency or empirical probability and it can be defined as a ratio of the number of outcomes for the occurrence of a specific event to the total number of trials in an actual experiment.
In order to make a prediction by using experimental probability, you should multiply the experimental probability by the total number of trials in an actual experiment.

180 degrees is the answer
Answer:
The probability that you get zero questions correct is 0.4096
The probability that you get one questions correct is 0.4096
The probability that you get three questions correct is 0.0256
Step-by-step explanation:
These probability can be describe with a Binomial Distribution. These distribution can be used when we have n identical and independent situations in which there is a probability p or probability of success and a probability q or probability of fail. Additionally q is equal to 1 - p. The probability of x for a situation in which we can apply binomial distribution is:
Where x is the variable that says the number of success in the n situations
And nCx is calculate as:
From the question we can identify that:
- n is equal to 4 multiple choice question
- p is 1/5 or 0.2, the probability of get one question correct
- q is 4/5 or 0.8, the probability of get one question incorrect
Then the probability of get zero questions correct of 4 questions is:
The probability of get one question correct of 4 questions is:
The probability of get three questions correct of 4 questions is:
I believe the answer is the first option. 1 to 3 with intervals of 1.
Hope this helps!
We have to divide 9/10 by 3/12.
if we divide by a fraction, we can instead multiply by it's inverse:
so now we count:
so we can cut exactly 3 pieces!
