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

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

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.
