The Cheap Mp3 Player
My MP3 player is cheap 'n' nasty and has now broken: it is stuck on 'Shuffle'. In this mode it starts with whatever track you put it on, but then plays tracks in a random order. The only restriction is it never plays a song that's already been played that day.
I purchased my favourite murder mystery book in audio format, and put the first 6 chapters on my MP3 player. (Each chapter is exactly 1 track.) There's nothing else on my player at the moment. What is the probability that I will hear the 6 chapters in order as I listen today, without having to change tracks at all? (Obviously, I will ensure it plays chapter 1 first.)
The next day I empty the player before putting on the next 6 chapters. This time I also transfer a CD of mine with 11 songs on. I don't mind songs coming in between the chapters of my book, as long as the chapters are in order. What's the probability of that happening now?

Hint:
With only 6 tracks on the player:
The first chapter has been set to play first. The probability of the next 5 chapters playing in order is 1/5! = 1/120.
With the music on the player as well:
Seeing as I don't care about when the music plays, it doesn't change anything. The answer is still 1/120. Did you answer this riddle correctly?
YES NO

On which day did the teacher say this?

It depends. The grammar is intentionally misleading; "yesterday was" is generally considered incorrect, but is still something people say. The speaker in the riddle may mean "I wish yesterday were tomorrow" or "I wish yesterday had been tomorrow", etc. So:
I wish yesterday (Wednesday) had been what tomorrow (Friday) will be = today is Thursday.
I wish yesterday had been Thursday so tomorrow would be Friday = today is any day!
I wish yesterday (Tuesday) had been [today's] tomorrow (Thursday), so that today (Wednesday) would be Friday (day after desired yesterday).
I wish yesterday (Saturday) would be [today's] tomorrow, then today (Sunday) would be Friday. Did you answer this riddle correctly?
YES NO
