Sample Space ={5 Red, 8White, 2 Blacks} = 15 possible outcomes.

Favorable outcomes={5 Red}

1) P(drawing 1st Red) = 5/15
2) P(drawing ANOTHER RED) = 4/14 (because one Red already drawn and NOT replaced, so the remaining Red are now 4 and the new sample space is now 14, since 1 red already drawn), Hence
P( 1 Red AND another Red) = (5/15).(4/15) or:

Suppose you just purchased a digital music player and have put 15 tracks on it. After listening to them you decide that you like
Lilit [14]
The given case is an example of permutation problem because the order is important given that you should like the first two songs. The sample space is calculated through the equation, 
                                       15P2 = 210
Then, there are 3 songs that you liked, the probability of picking 2 out of them is,
                                         3P2 = 6
Dividing the latter by the earlier result will give us an answer of 1/35.
