"WebThese types of random number generators are called ‘Hybrid’ RNGs. Bias Most sources of random data generate ‘biased’ output, i.e. the chance that an output bit is ‘1’ or ‘0’ is not equal to 0.5. In other words, the source generates more ‘1’s than ‘0’s, or vice versa. " - Cryptographic random number generators
