Why linear congruential generator is called random number generator?

As far my understanding linear congruential generator is used to produce pseudo random number. But the algorithm requires four parameters like,def lcg(modulus, a, c, seed): while True: seed = (a * seed...

Why are sizes of infinite sets equal if theres a bijection between them?...

We think of finite sets A and B having the same size whenever we can draw a one-to-one correspondence between the elements in A and B, and vice versa, which is based on our intuition for finite sets....
