prob = .5 on 160 outcomes.
I only have excel. Anysuggestions of free shareware on net? to do this
thx

Take a look

thanks for the website..but soory my request wasn't clear..i can generate function
in excel..but i ned to draw/plot it?

any ideas

thx

Calculate over a grid of {0,150} say x=0 to 150 by 5 (if not 1) ,thats axe-X,the cumulative of the binomial,thats axe-Y, and plot them

Many like it in log scale

If using R

x<-0:150
plot(pbinom(x,prob=.5,size=150),type="o",col="red")
