Fitting poisons distribution means finding expected frequencies of

X:0,1,2,3,4,5,6,7,8

Now mean =bixiBi=mBixi=500=Nm=986500=1.972

Poissons distribution of x is

P(X=x)=em×mxx!=e1.972×(1.972)xx!

Expected frequency =N×P(x)=500×e1.972×(1.972)xx!

Now putting X=0

we get P(X=0)=e1.972×10!=0.1392

Expected …
