5,266 PointsQuestion about Random.Next and Random.NextDouble
Where can you see the range of numbers that Random.Next chooses from, since its a pseudo random number then there are are finite list of numbers it chooses from. Also with Random.NextDouble could it ever be exactly 0.500000000000?

Pseudo-random does not imply choosing from a list.
That might be one method for generating pseudo-random numbers, but an even more popular method is to employ a mathematical expression that computes a large value and then extract a subset of bits from it.
Predicting if a specific number will be generated by such a method is also difficult. You might be more likely to answer the question by calling the function in a loop and checking against the desired value. It may take very many iterations to prove a "yes", and it may not be possible to be 100% certain about a "no".
