I was feeling so frustrated about the "Details - MP3 Artefacts" challenge on the "Silver Ears" level that wrote the below e-mail to the e-mail address found on the “Golden Ears” site, However, I haven't received any reply, and I sort of doubt that I ever will. Anyway if I do receive a reply I'll publish it here.

MP3 Artifacts" challenge only have 4 questions

Just keep guessing if you lucky u will pass it

If I remember the little mathematics about statistics I once learnt, the likelihood is about 1 chance in 25 I’ll be able to guess it provided I’m able to nail 96 Kbps without guessing. Provided I don’t need to guess at 112 Kbps the odds increases to about 1 chance in 10. No, I don’t think this method will work for me. Thanks for the suggestion nevertheless!

Guessing four: (1/3) * (1/3) * (1/3) * (1/3) = 1.2 % (1 chance in 100)

Guessing three: (1/3) * (1/3) * (1/3) = 3.7 % (1 chance in 25)

Guessing two: (1/3) * (1/3) = 11.1 % (1 chance in 10)

Guessing one: (1/3) = 33.3 % (1 chance in 3)
