Using it's concept, the experimental probability that in a group of 4 students, at least one of them has green eyes is of 0.45 = 45%.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>. An experimental probability is calculated considering the results of previous trials.
In this problem, there were 20 trials. The digit 9, which represents a student with green eyes, appears at least once in 9 of the the trials, hence the probability is:
p = 9/20 = 0.45 = 45%.

For number 4 the equation is 12 divided by 3/4 and when you solve that you get 16 which is the answer. For question 5 the equation would be 40 5/8 divided by 4. The first to do this is make 40 5/8 an improper fraction which is 325/8. Then you would flip the 4/1(this is the same thing as 4) to get 1/4. Then you would multiply 325/8 * 4 to get 325/32 and as a mixed number 10 5/32 which is the answer.

Step-by-step explanation:
For example if you have a function f(x) = x - 1, then x = 1 is a zero of this function because using it as x gives 1 - 1 = 0. The Riemann Zeta function has some zeros that are easy to find which are of little interest but there are some other ones that are harder to find which is why the are called non-trivial.
