She has a 73% chance that the first track she plays is a track she likes. Because there are a total of 11 tracks. One track that's her favorite, 8 that she likes and 2 she dislikes which is a total of 11. Then divide 8 by 11 and you get 0.72727272 and so you round and convert it into a percentage which is equal to 73% which also equals to 8/11 chance.

3 0

1+2+8= 11
And she likes 8 out of the 11 tracks

So the probability is 8/11 or about 73%
