Binomial and poisson

When using the tables for the binomial and poisson distributions, does it matter if the sign is 'less than' or 'less than or equal to'/'more than' or 'more than or equal to'?

Yes the tables give you the values for less than or equal to

Yes - they are discrete distributions: $\mathbb{P}(X < k+1) = \mathbb{P}(X \leq k)$ - the tables give values for $\mathbb{P}(X \leq k)$.

So if you wanted to compute $\mathbb{P}(X < 5)$ where $X$ is distributed binomially or with a poisson distribution using the tables, you would need to convert this to $\mathbb{P}(X \leq 4)$ then look up $4$ using tables.

Cool, thanks
And just checking, but normal tables are continuous, right? So for them it doesn't matter if its 'less than' or 'less than or equal to'
