EXPLANATION:

Given;

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

$\begin{gathered} Green\text{ }eyes=6 \\ Blue\text{ }eyes=5 \\ Hazel\text{ }eyes=9 \end{gathered}$

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;

$P[Event]=\frac{Number\text{ }of\text{ }required\text{ }outcomes}{Number\text{ }of\text{ }all\text{ }possible\text{ }outcomes}$

To calculate the probability that a selected student will have green eyes;

$P[green]=\frac{6}{20}=\frac{3}{10}$

To calculate the probability that a selected student will have blue eyes;

$P[blue]=\frac{5}{20}=\frac{1}{4}$

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;

$P[G]+P[B]=\frac{3}{10}+\frac{1}{4}$ $P[F]+P[B]=\frac{6}{20}+\frac{5}{20}=\frac{11}{20}$

Therefore,

ANSWER:

$P[G\text{ }orB]=\frac{11}{20}$

Answer:

1. Question isn't complete. It says "Which gives the first two steps to evaluate" and cuts off.

2. Seems like 3.(4-2)2+1 if 3. means to multiply.

3. 9.1=9 should be the answer if . means to multiply.

4. 10x+0=10x

5. x=3 or y=-8

6. x=5 or y=-6

7. Not so sure about this one.

8. 7x/9y

9. 5

Step-by-step explanation:

2. 3.(4-2)2+1

3(2)2+1

6(2)+1

12+1
