Poisson Distribution - on a standard calculator
hello , can Poisson Distribution problems be worked out on a standard
here is a question ive been trying to solve
If there are 150 typographical errors randomly distributed in a
600-page manuscript, find the probability that any given page has exactly 2 errors.
the solution (2.7183) - 0.25 * (0.25)2 / 2!
the answer given is 0:024
my problem is this part (2.7183) - 0.25
can it be done on a standard calculator ?
if so how?
i apologize for being Old Fashioned
but i like my standard calculator! (Worried)
