Hi juantheron;
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Re: probability
probability of catching of fire = 2/2000.
probability of not catching of fire=1- 2/2000 = 999/1000
probability of atleast one house catching fire = 1 - probability of not catching of fire = 1-999/1000 = 1/1000.
