This sounds like a potential homework problem. You don't quite need to simulate anything if your question is all you have been asked to do.
dbinom(x = 1:10, size = 10, prob = 0.25) Perhaps you have been asked to simulate 1000 realizations and compare the relative frequencies with these probabilities: use rbinom(n = 1000, size = 10, prob = 0.25) in that case and compare the relative frequencies. Btw, there is a small chance of getting a 0. Are you sure the instructor (or whoever has issued the orders) wants only from 1:10? HTH!
