Math related question about a playlist
This isn't really a Winamp issue, but I have a question about a playlist.
I have a playlist that has 352 songs. I'd like to add a certain amount of Christmas songs so that the likelihood of one being played is 1/4 or .25. How would I figure out how many to add in? I know its got to be simple math but I'm just not thinking about it right.

#of xmas songs/#total songs = 0.25 Here's the algebra involved. Let X = Number of songs to add X/(352+X)=0.25 X = 88+0.25X 0.75X=88 X = 117.3(Repeating) Since there is no way to add .3(Repeating) songs, just round down. This will make the probability slightly lower than .25 (somewhere in the neighborhood of .2494 .. which obviously is VERY close to .25 You can round up to 118 to have a slightly higher chance 0.25106 Good luck, Davis

If algebra isn't your bag, just divide 352 by 3, since 352 is going to represent 3 fourths of your playlist.

Ah, that's what I was doing wrong! I was dividing 352 by 4 when I should have been dividing it by 3. Thanks for the help and hope you all have a great Thanksgiving!
