How much energy is supplied to each coulomb of charge that flows through a 12-v battery?

Energy supplied to the charge is given by

here we know that

also we have

now we have

so the energy given by battery will be 12 J

The correct answer to this question is that "The experimental probability is 1/15 less than the theoretical probability."

The table as attached via image shows that the probability of getting a Jack is 2/5, getting a Queen is 4/15, and King is 1/3. That is the theoretical probability of each card to be drawn according to its frequency.
