So for this one are we assuming it's a fair coin, or probability p that it will flip heads? Does it matter?
I really don't think it matters, you only have two outcomes H or T. And for this you're finding the possible ways each event could occur. And the probability that the event will occur it the number of possible outcomes for that event divided by the total number of outcomes. Hope that helped! ---Kristen 19:42, 18 February 2009 (UTC)
In parts B&C, where it says "two, and not three, heads come up in a row" could you still have TTHHT, or does it have to be HHT? -Stephanie
The only elements of the set that the two heads, but not three apply to are the HHT, THH out of the total 8. (HHH) does not apply.
-mkburges
The coin is only flipped 3 times, so I don't think TTHHT is possible.
