Generate Random Boolean Probability

Question

I only know how I can generate a random boolean value (true/false). The default probability is 50:50

But how can I generate a true false value with my own probability? L

Answer 1

Assuming your probability is represented as double between 0.0 and 1.0, I would implement it more simply like this:

Random rand = new Random();
...
double trueProbability = 0.2;
bool result = rand.NextDouble() < trueProbability;

result will be true with the probability given by trueProbability

If this isn't "random enough", you can take a look at RNGCryptoServiceProvider:
