Question

Some please help with this problem, I have tried multiple time but still couldn't get the right answer. :(

Answer 1

Given data:

Total number of songs = 8

Rock songs = 3

Reggae songs = 2

Country songs = 3

Probability = Number of favorable outcomes / Total number of outcomes

To find:

When song is selected randomly to play first song and then second song from remaining ones ,

Probability when both the songs are from Reggae songs,

$\begin{gathered} P\text{ =}\frac{2}{8}\times\frac{1}{7} \\ \text{ = }\frac{2}{56} \end{gathered}$$P=\frac{1}{28}$

Thus , the probability is 1/28.
