    Two events, A and C, are independent if the fact that A occurs does not affect the probability of C occurring.

    When two events, A and B, are independent, the probability of both occurring is: P(A and B) = P(A) P(B)

    (13/52)(12/52)=(1/4)(12/52)=12/208=6/104=3/52=0.0577?

    'Whats goin on' is that you should have worked with exact values and done the basic arithmetic by hand instead of running to a calculator and getting decimal approximations (clinically proven to cause brain rot).
