Here is some help with the first several problems:
1) The chance of getting heads in 1/2. Because there is 1 head and there are no sides to the coin.
2) You have the same 1/2 chance of getting tails.
3) If you tossed a coin 100 times, you would expect 1/2 of them to be heads because the chance is 1/2 per coin. That would be 50 times.
