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%.

probability of drawing ace: 4/52 = 1/13
probability of drawing 9: 4/52 = 1/13
probability of drawing ace or 9: 1/13 + 1/13 = 2/13 or ~15.4%
Answer:
52
Step-by-step explanation:
2(4^2 + 10) =
We do what's in the parenthesis first.
4^2 = 16 and 16+10 =26.
2(26)
= 52
