On Monday, you flip a coin all day. You start flipping it until you see the pattern Head, Tail, Head. You record the number of flips required to reach this pattern, and start flipping again (and counting up from 1 again) until you see that pattern again, you record the second number, and start again. At the end of the day you average all of the numbers you’ve recorded.
On Tuesday you do the EXACT same thing except you flip until you see the pattern Head, Tail, Tail. Will Monday’s number be higher than Tuesday’s, equal to Tuesday’s, or lower than Tuesday’s? No Googling for the answer! |

 I've seen this problem before. I couldn't figure it out and when I finally read an explanation I was thinking "OOooooohhhhh! Now I get it!" |
