This question is about testing for randomness.
Suppose israndomsequence is a Python procedure
that takes as input a sequence of bits--that's input s--
and it outputs true if that sequence is truly random
and false otherwise.
The 2 statements are it's actually impossible to implement
a procedure that does this.
If some source produces random sequences
that are guaranteed to pass an israndomsequence procedure
that behaves as described, than that source cannot
be a true random number generator.
Check all the true statements.
