dbinom returns the discrete density of the binomial distribution, which
is in your case .75 at 0, .25 at 1 and 0 elsewhere (such as at 10).
Is dbinom(0:10, 10, .25) what you are driving at?

Not being entirely sure what you mean, I think
rbinom(1000, 10, .25)
may be what you want.

Johannes Hüsing There is something fascinating about science.
One gets such wholesale returns of conjecture
