hey.. plz can u explain how plz plz

anonymous · Answer

No, because the removal of the first ticket lowers the number of tickets in the raffle, thereby affecting the probability of your ticket being drawn the second time around.

@paulm... u mean that next time there is still chance for me ?

What I mean is that if, for example, there are 100 tickets in the raffle at the start, after the first drawing there will be 99 tickets. This takes the probability of winning from 1/100 to 1/99, and since the first event affects the probability of the second event, the events are dependent.
