In a genetics class, 6 students have GREEN eyes, 5 students have BLUE eyes, and 9 have HAZEL eyes. If a single student is picked

mixer [17]

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:

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

J<br> L<br> N<br> M<br> If mZJKN = 28º and mZKLM = 103°, find mZJML.

Bingel [31]

Answer:

98°

Step-by-step explanation:

each half adds up to 180° so 103+28=131 then 180-131=49

and that would be just one of the bottom angles so you would double it to get 98

Bao is mixing flour and water to make dough the graph shows how much water he uses for different amounts of flour .How many lite

Allushta [10]

To know how many liters of water Bao use per liter of flour we have to divide the liters or flour so:

$\frac{1}{3}=0.33$

So Bao uses 0.33 or 1/3 of water per liter or flour

and to know hoy manu liters of flour Bao use per liter of water we have to made the oposite division so:

$\frac{3}{1}=3$

She use 3 liters of flour per liter of water
