But- there is another solution! It is unknown! For others could have eaten other stuff!
Arbelle, in your answer you can't make 2, 5, and many other numbers. I don't think you understood this but here is another riddle similar to this
You come across a bank. You come to withdraw coins. There are 1,083 coins in your bank acount. You want to make sure you can get any amount of money the quickest unless it's more than 1,083. How do you divide the coins? If you don't answer right then you will be late for work, lose your job and living, and become a hobo. So you better act quickly in 1,000 sec. 999 sec. 998 sec...
SSS HHH TTT is 3 of the same.
SHT SHH SHS is SH, STH, STT, STS is ST. SST, SSS, SSH is SS, Is S.
3x9=27. 27+3=30. 3 out of 30= 1 tenth.
There is a 1 out of 10 chance of getting 3 of the same, 9 of 10 of getting something else. A 10% chance to get 3 the same.
Ok now not exactly will there be 2 the same. Let's say you get a side. Heads=H Tails=T Side=S. Side isn't impossible but rare. It's like a 10% chance to get a side. 3.3% of getting 3 sides. Now 87.7% is left. About 11% to get 3 heads or tails. 33% to get 1 tail/head. So like a 25.3% chance to get 3 of the same things.
