After all of the other insane mathematical odds on top of this one, we finally get to the example of the Atlantic ocean in the Infographic.
What are the odds that the one egg (Sally) met the one sperm (Harry) which together made you and not your brother?
1 in 400,000,000,000,000,000 (1 in 400 quadrillion) which is ~ the volume in cubic meters of the Atlantic Ocean. (3.236x10^17 Cubic meters)
...and then the calculations morph into more insane figures.
