Have you tried to express P{X<=2} in terms of lambda?

Do you not know the probability mass function of the Poisson distribution?
$P(X \leq 2) = \sum_{k=0}^2 e^{-\lambda} \frac{\lambda^k}{k!}$

yeah, I tried doing that, but how do you go about integrating this to the first part of the question he gave?

You plug in lambda=0.3 and lambda=1.8

you should go back to the probablity textbook and read again the definition of poisson distribution. furthermore you should go back to your precalculus textbook to learn how a sum works

Just not been able to make it work

what the fuck is this
all i know is that probability is the ratio of possitibilities that meet some constraints and the total amount of equally likely possilibilities
