Calculating Probability using C#
Posted on 2009-03-29
I'm wondering how to approach a problem of calculating probability in C#.
Lets say, we know that some task has a 5% probability of happening and there're say 100 identical tasks. So theoretically, 5 tasks should happen, but as those tasks are individual tasks, each task has a 5% probability of happening. So, how can I simulate this case using programming?
I presume that I can get 5 random number using Random class (Random rand = new Random(); rand.Next(1, 100)), and then get another 100 numbers and see if any number is in the set I generated first. But in this case, it's not truly random as generating first 5 numbers can use all "random potential" of these numbers and they will happened to be generated again.
Is there any accurate way of doing it?
