Answer:

Step-by-step explanation:
we are given 8 songs
2 are <em>rock.</em><em> </em>4 are <em>reggae</em>, 2 are <em>country</em>
we want to figure out the probability of getting both reggae songs
notice that, they aren't replacing thus it's an independent probability
recall that,

P(A) represents the chance of getting our subject first time and P(B|A) represents the chance of getting the same subject second time
let's figure out P(A)
we have 2 reggae songs
and total 8 songs
therefore

let's figure out P(B|A)
since we took a reggae song before now we have only a reggae song
and total 8-1=7
therefore

Altogether

simplify multiplication:

And we are done!

Answer:
The equation for the following graph:

Step-by-step explanation:
- You first need to find the slope by using the <u>slope formula</u>:

(where
is the first point and
is the second point)
-Use the given points
and
from the graph for the formula:

Then, you solve:


After you have found the slope, use the slope
and the first point
for the <u>point-slope formula:</u>

<u>(</u>where
is the slope and
is the first point)

Then, you solve:




So, the equation for the following graph is
.
