Help with Poisson Distribution (stats)
Hi guys I got a question on the poisson distribution and never previously done stats at all.
It follows:
The mean count of a radioactive substance is 25 disintegrations per minute. Using the Poisson distribution, find the probability that, in a time of 12 seconds, there are-
i) No disintegrations
ii) More than 2 disintegrations
It follows:
The mean count of a radioactive substance is 25 disintegrations per minute. Using the Poisson distribution, find the probability that, in a time of 12 seconds, there are-
i) No disintegrations
ii) More than 2 disintegrations

25 per minute is the same as 5 per 12 second interval so you use the Po(5) distribution.
