I just don't know how to do this, please help

Problem 2 (5 pts). On a computer, plot the binomial distribution as well as its normal approximation as a function of a: with n = 20 and p = q = 1/2. You may as well treat a: as a continuous variable, if that will make your plot easier. It is best if you can display both distributions on the same graph. Do the two look \"close\" enough to each other? Binomial distribution: f(a:) = C(n,a')p""q\"_$. Normal distribution: \"e(\"*le/zgz. Here C(n, r) = nl/rl(n r)!, p is the probability of 'success.' q is the probability of 'failure,' and the standard deviation of a: is o 2 Mn
