If an event occurs 2.5 times a second, and every time it happens, there's a 20% chance that the event will no longer occur afterwards, how do I find the average amount of occurrences of the event?

Answer 1

This is a geometric distribution:

Since there is a 20% chance that the event will NO LONGER occur again

Given p = 0.2

By the formula of the mean of geometric distribution,

ANS:

1/p = 5
