Hi,

i need to remove strings in an ArrayList<String> by a small random probability (10^-7). My idea was to set a boolean if the string must be removed, that boolean should be false. So i wrote following code

    public boolean shouldSequenced() {
    boolean decision = false;
    double prob = Math.random();
    if (prob > Math.pow(10, -7)) { 
        decision = true;
    }
    return decision;
}

My problem is now that Math.random() generates always numbers higher than 10^-7 so i will never set the boolean to false. And if i multiply "prob" with 10^-7 i will be always smaller than 10^7 and would set my boolean always false. Has anyone an idea how to solve this?

Thanks in advance for your help.
