..

lol, nevermind. Reading your thread on Ubuntu vs XP and watching that video pretty much confirms that you're trolling.

The point was to prove with a blind test video that I'm not trolling. PCM and FLAC are not identical because FLAC uses 1% CPU power while PCM uses 0%. I used the default VBR values, I don't know what it is, but it sounds different than 320 cbr.

First calculate all possibilities (4 options, 6 trials): 4^6 = 4096

Then calculate combinatorial: 5/1 = 5

Then calculate how many ways to answer 1 wrong = 3^1 = 3

Then multiply them: 5*3 = 15 (there are 15 possibilities to answer 5/6 correct)

Then divide with all possibilities with that number: 4096 / 15 = 273

Add possibility of answering 6/6 (+1 possibility): 4096/16 = 256

It is

Possibilities: 4^9 = 262144

Combinatorial: (9*8) / 2 = 32

Answer wrong: 3^2 = 9

Multiply: 32*9 = 288

Divide: 262144/288 = 910

Add 8/9: (9/1)*(3^1) = 27

Add 9/9: 1

288 + 27 + 1 = 316

Divide: 262144/316 = 829.57

Possibilities: 4^11 = 4194304

Combinatorial: 11*10*9*8 / 4*3*2*1 = 330

Answer wrong: 3^4 = 81

Multiply: 330*81 = 26730

Divide: 4194304/26730 = 156.9

Add 8/11: ((11*10*9) / (3*2*1)) * (3^3) = 4455

Add 9/11: ((11*10) / (2*1)) * (3^2) = 495

Add 10/11: (11/1) * (3^1) = 33

Add 11/11: 1

26730 + 4455 + 495 + 33 + 1 = 31714

Divide: 4194304/31714 = 132.25
