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%.

It’s b I’m positive because I did 1.25 to the power of 3 and put that into fractional form
Answer:
![\blue{y = \dfrac{C + 2k}{2}}](https://tex.z-dn.net/?f=%20%5Cblue%7By%20%3D%20%5Cdfrac%7BC%20%2B%202k%7D%7B2%7D%7D%20)
Step-by-step explanation:
![C = 2(y - k)](https://tex.z-dn.net/?f=%20C%20%3D%202%28y%20-%20k%29%20)
![C = 2y - 2k](https://tex.z-dn.net/?f=%20C%20%3D%202y%20-%202k%20)
![C + 2k = 2y](https://tex.z-dn.net/?f=%20C%20%2B%202k%20%3D%202y%20)
![\dfrac{C + 2k}{2} = y](https://tex.z-dn.net/?f=%20%5Cdfrac%7BC%20%2B%202k%7D%7B2%7D%20%3D%20y%20)
![y = \dfrac{C + 2k}{2}](https://tex.z-dn.net/?f=%20y%20%3D%20%5Cdfrac%7BC%20%2B%202k%7D%7B2%7D%20)
Answer:
The possible values of x is given by
and they include: -2, -3, -4, -5, -6 and so on
The greatest possible value of 7x is ![-14](https://tex.z-dn.net/?f=-14)
Step-by-step explanation:
We are given the equation: x + 8 <= 6
Let collect the like terms:
![x + 8 \leq 6\\x\leq 6 -8\\x \leq -2](https://tex.z-dn.net/?f=x%20%2B%208%20%5Cleq%20%206%5C%5Cx%5Cleq%20%206%20-8%5C%5Cx%20%5Cleq%20%20-2)
Therefore, x <= -2 and the possible values include: -2, -3, -4, -5, -6 and so on
To find the greatest possible value of 7x is when x = -2.
