Plotting a binomial distribution formulae in excel?

Need assistance on how to plot this formulae in Excel.
(N choose K)K^P(n-k)^(1-p)

What are you looking to use as your variable? n,k, or p?

Use a compter (excel) to plot the binomial distribution as a function of k
for n=50, and p=0.7

By the way, you have the binomial distribution formula wrong, it's:
(N choose K)(p^K)(1-p)^(n-k)

But to answer your question, place this formula in A1 and drag down to row
50, then select the range A1:A50 and graph:

=COMBIN(50,ROW())*(0.7^ROW())*(0.3^(50-ROW()))

Maybe you could use the BINOMDIST worksheet function to get values on a
worksheet and then create a Column chart type.
