On the basis of mathematical theory, the chance of occurrence of any event is called theoretical probability.
For example if we toss a coin then the probability of a head and a tail is half half i.e 0.5.
But the probability calculated by repeated experiments and examine the outcomes are called experimental probability.
For example if we toss a coin 20 times and got 9 times head and 11 times head then the probabilities are given by
These probabilities are different what we got in case of theoretical probabilities.
Using the proportion concept, it is found that:
- According to Tyler's sample, the estimate is of 0.2 = 20%.
- According to Kyran's sample, the estimate is of 0.17 = 17%.
- Due to the higher sample size, Kyran's estimate is more accurate.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and larger sample sizes lead to more accurate predictions.
In Tyler's sample, 2 out of 10 students would dye their hair blue, hence:
p = 2/10 = 0.2.
In Kiran's sample, 17 out of 100 would, hence:
p = 17/100 = 0.17.
Due to the higher sample size, as 100 > 20, Kyran's estimate is more accurate.

Answer:
of oil are needed for each cup of vinegar.
Step-by-step explanation:
Given:
A recipe of salad dressing calls for ¼ cup vinegar to ⅔ cup oil.
Now, to find the cups of oil are needed for each cup of vinegar.
So, we solve by using unitary method:
If 
cup of vinegar is needed for oil of 
cup.
So, 1 cup of vinegar is needed for oil of = 
= 
(the fractions turns reciprocals as the division changes into multiplication)
= 
= 
cups.
Therefore, of oil are needed for each cup of vinegar.
Answer:
yes it is!!
Step-by-step explanation:
It is important to Remember the negative exponent law.
X^-m = 1/X^m
1/10^2 = 10^-2.
