If I've got two scheduled daily flights leaving an a airport on a given day and the historical data says they both leave on time 50% of the time, then there is a 25% chance they both leave on time that day...
ONLY if they have never been delayed on the same day for the same reason. Otherwise they're not independent events; the outcome of one correlates with the outcome of the other.
E. Kipchoge has run 9 marathons and not broken the WR once. So his chances are less than 1 in 9, but probably more than 0. Let's take the halfway point, 1/18.
T. Dibaba has run 3 marathons and not broken the WR once. The same calculation gives us 1/6 for her.
So the chance of both happening is approximately 1%.
