What's the correct answer?
Have you tried ?
This would make sense to me since
I just got a question in my exercise book that I tried to attempt but continually got the wrong answer. I am asking here to see if it was my problem or the books. The question is really quite simple:
Y is distributed as a poisson distribution. When m = 2.7 (mean) find
I thought it would just be the probability of as all events are independent. However, this is not the correct answer.
I tried to do it using the formula for conditional probability but of course as they are independent this did not work.
A progression of the solution would be appreciated.
