Question

If the probability of getting an event is 0.04, then the probability of not getting that event.​

Answer 1

The most important thing while solving the questions related to probability is that the sum of all observations is 1.

Here, we see that the occurrence of the event is 0.04, hence the probability of the event not occurring is 1 - 0.04 = 0.96.

Now, when it is repeated 250 times and in all cases it does not occur :

0.96 * 0.96 * 0.96…250 times

0.96 ~ 1. Hence the answer here is 0.96^250 or a bit less than 1.
