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:
6x10 to the power of 21 the answer is too long for my calculator sadly
Answer:
0.84545454545
Step-by-step explanation:
First is solve the total volume of punch they made. but convert first the 5 L to ml.
for every 1 L there 1000 ml, 5 L ( 1000 ml / 1 L ) = 5000 ml of punch
V = 5000 ml + 750 ml
V = 5750 ml
then number of 180 ml serving
n = 5750 / 180 = 31.94 or about 31 servings of 180 ml was made.
the punch left over
v = 5750 - 180( 31) = 170 ml of the punch is left
how to use the scale factor to 56
