Question

A coin is flipped 25 times. How many ways can we get exactly 19 heads?

Answer 1

177,100 ways

Explanation:

"If you number the flips 1 through 25, then each different combination of 19 heads from the 25 total is considered different. So 25C19 = 25C6 is the number of distinct U Tube videos you could watch to yield your outcome. So it is 177,100 ways."
