1.6 billion
You can think about this in a lot of ways, but here's one way to do it in your head:
- 64 is 8 times 8.
- That means 64 is 16 times 4, and 6.4 is 1.6 times 4.
- So 6.4 billion divided by 4 is 1.6 billion.
64 billion divided by two thousand is 32,000,000
0.0312
0.0128
0.0625
0.1753
3.125
64 divided by 4 is 16.

If you mean there will be 4 billion winners from a population of 64 billion people - the odds are 16:1
