A radio disc jockey has 8 songs on this upcoming hour's playlist: 2 are rock songs, 4 are reggae songs, and 2 are country songs.

Answer:

$\displaystyle \frac{1}{28}$

Step-by-step explanation:

we are given 8 songs

2 are rock. 4 are reggae, 2 are country

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,

$\displaystyle \rm P(A \: \text{and} \: B) = P(A) \times P(B \mid A)$

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

$\displaystyle\rm P(A) = \frac{2}{8} = \frac{1}{4}$

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

$\displaystyle \rm P(B\mid A) = \frac{1}{7}$

Altogether

$\displaystyle \rm P(A \: \text{and} \: B) = \frac{1}{4} \times \frac{1}{7}$

simplify multiplication:

$\displaystyle \rm P(A \: \text{and} \: B) = \frac{1}{28}$

And we are done!
