Now, back to your problem. You will be performing the same experiment
5 times in succession; that is, flipping a coin. Each flip of the
coin can result in 2 distinct and equally likely outcomes, H or T.
Moreover, the result of any coin flip is not influenced by or
dependent upon any previous coin flip. That last statement regarding
independence of the coin flips is very important; it tells us that all
possible outcomes after 5 coin flips are equally likely, or have the
same probability.
