Your answer is right, exact one is of binominal distribution, and it can be approximated by poisson distribution with lambda=50*0.01

#

Exact answer=1-pro(num of AB-=0)-pro(num=1)

#

which can be approximated as 1-poission(lambda=0.5, k=0)-poission(lambda=0.5, k=1)

#

Sure

#

Sure

#

in practical case, lambda shows the average of arrivals in unit time.

#

You should firstly understand what poission distribution means. It is of counting numbers of happenings(arrivals, erros, requests to server, ...) in unit time.

#

Poission is absolutely not related to attempt. Binormial dist is.

#

In the above problem, the knowledge is about the approximation of BI with Po(lambda)

#

lol, n is for Bi, lambda is for Po. So you see now?

#

No problem
