Function: S(p,N) = 1 - (1-p)^N
Plot a two-dimensional surface showing that probability: S(p,N), 0p1,2N10,000.

Right but you still need to define what those values are for p. Is it sufficient to do something like
p = 0:0.01:1;
where the array p is all values 0, 0.01, 0.02, 0.03,..., 1.0? Or do you need more or fewer? Once you have determined that and done something similar for N (this is probably easier and you could use your code above), then you can use meshgrid as
[P,N] = meshgrid(0:0.01:1, 2:1:10000);
and then put those results in your above function. Then try using contour that Aquatris described below.

What you are looking for is the "countour" function (or countourf) of Matlab. Check this link and you can adapty your equation to the given example.

Dont exactly know your values but something like this;
p = linspace(0,1,1e3);
N = linspace(2,1000,1e3);
[X,Y] = meshgrid(p,N);
Z = 1-(1-X).^Y; % notice the .^ since we do not want matrix algebra
