Performing functionality for a minimum of n% in x cases

Say I have a loop of 100 where every time I run it, 40% of the time I always have to do function A, 30% of the time I have to do function B and the remaining 30% I have to do C.

So far I have found this which doesn't exactly solve my problem as there is always the possibility of not performing the minimum amount required.

Is there something else I could use which could help me? Also these percentages have to calculated at runtime.

Create a list containing 1 to 100, shuffle it, then use those values drawn sequentially to determine which function to execute:

List<Integer> list = new ArrayList<>();
for (int i=0; i < 100; ++i) {
    list.add(i);
}
long seed = System.nanoTime();
Collections.shuffle(list, new Random(seed));

// now here is your loop
for (int i=0; i < 100; ++i) {
    if (list.get(i) < 40) {
        A();
    }
    else if (list.get(i) < 70) {
        B();
    }
    else {
        C();
    }
}
