Step 1
If this is truly a binary event (either the event will happen or the event will not happen, there are not other options) then the probability of the event happening and the probability of the event not happening is 100% or 100 100
Therefore, the probability of the event happening, let's call it p h is equal to 100 100 minus the probability of the event not happening, let's call it p n .
Step 2
Or p h = 100 100 - p n .
We know p n = 87 100 so we can substitute and solve for p h .
p h = 100 100 - 87 100 = 100 - 87 100 = 13 100
The probability of the event happening is 13 100
