How many different sequences of ten flips of a coin have at least 8 heads?

There are 1024 different possibilities of the side the coin will land on when flipped. (2x2x2x2x2x2x2x2x2x2)

Now, we have to determine how many of those will have 8 heads.

Or you could simply possibly find

8/10, 9/10, and 10/10, which are the 3 sequence possibilities.

Its 50/50, a game of luck say to so.
