Question

What did the girl rock say to the boy rock

Answer 1

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.
