Adapting the binomial options pricing model and compound probability we should be able to return the sum of f(1) over 30 trials to give us equal probability in returning [0..29]

The probability is going to be .5^29

```
public static int f29() {
int start = 0;
int randomPick = 0;
while (start <= 29) {
randomPick += f1();
}
return randomPick;
}
```
