Binomial distribiuton

[gutierrezs]

For P(X<6) with n=20 and p=.3.

Why would you choose the upper bound that you did and if you were using the normal approximation could you choose a different upper bound? Why or why not?

So for this problem, I found the P(x<6) to equal .416371.
What I do not understand is what the upper bound is.

What do you mean by upper bound? Upper bound of what? Sorry but I am not understanding your question.
