The experimental probability that in a group of 4 students, at least one of them has brown eyes is 95%.
<h3>
What is Experimental Probability?</h3>
Experimental probability is a probability that is determined on the basis of a series of experiments. A random experiment is done and is repeated many times to determine their likelihood and each repetition is known as a trial. The experiment is conducted to find the chance of an event to occur or not to occur.
Here , Favorable Outcome = 19
Total outcomes = 20
Probability = Favorable Outcome/ Total Outcome
= 19 / 20
= 95%
Thus, the experimental probability that in a group of 4 students, at least one of them has brown eyes is 95%.

Answer:
Step-by-step explanation:
let a be the number of tennis balls.
let b be the number of tennis rackets.
We write determine the ratio of balls to rackets by dividing the number of balls by the number of rackets:
For every one ball, there 5 thirds of a racket.
We plot this function on a graph to visualize our model;
