EXPLANATION:
Given;
We are given that in a class there are the following groups of students;

Required;
We are required to calculate the probability that a student selected at random will have Green eyes OR Blue eyes.
Step-by-step solution;
To calculate the probability of an event, we shall use the following formula;
![P[Event]=\frac{Number\text{ }of\text{ }required\text{ }outcomes}{Number\text{ }of\text{ }all\text{ }possible\text{ }outcomes}](https://tex.z-dn.net/?f=P%5BEvent%5D%3D%5Cfrac%7BNumber%5Ctext%7B%20%7Dof%5Ctext%7B%20%7Drequired%5Ctext%7B%20%7Doutcomes%7D%7BNumber%5Ctext%7B%20%7Dof%5Ctext%7B%20%7Dall%5Ctext%7B%20%7Dpossible%5Ctext%7B%20%7Doutcomes%7D)
To calculate the probability that a selected student will have green eyes;
![P[green]=\frac{6}{20}=\frac{3}{10}](https://tex.z-dn.net/?f=P%5Bgreen%5D%3D%5Cfrac%7B6%7D%7B20%7D%3D%5Cfrac%7B3%7D%7B10%7D)
To calculate the probability that a selected student will have blue eyes;
![P[blue]=\frac{5}{20}=\frac{1}{4}](https://tex.z-dn.net/?f=P%5Bblue%5D%3D%5Cfrac%7B5%7D%7B20%7D%3D%5Cfrac%7B1%7D%7B4%7D)
The probability of event A or event B will be the addition of probabilities.
Therefore, the probability that a randomly selected student will have green or blue eyes will be;
![P[G]+P[B]=\frac{3}{10}+\frac{1}{4}](https://tex.z-dn.net/?f=P%5BG%5D%2BP%5BB%5D%3D%5Cfrac%7B3%7D%7B10%7D%2B%5Cfrac%7B1%7D%7B4%7D)
![P[F]+P[B]=\frac{6}{20}+\frac{5}{20}=\frac{11}{20}](https://tex.z-dn.net/?f=P%5BF%5D%2BP%5BB%5D%3D%5Cfrac%7B6%7D%7B20%7D%2B%5Cfrac%7B5%7D%7B20%7D%3D%5Cfrac%7B11%7D%7B20%7D)
Therefore,
ANSWER:
Answer:
Answer is A.. ( i.e. 3x + 7 )
Answer:
1 and 0
Step-by-step explanation:
sin(
) = 1, hence
sin³(
) = 1³ = 1
cos(
) = 0, hence
cos³ (
) = 0³ = 0
