Question

Find the probability of getting a difference of 4 or 6 from a diamond card.

Answer 1

Answer:

The answer is 17/52.

Explanation: The number of diamond cards is 13, and the number of '6' cards is 4.

Picking one diamond out of 13 is 13C1, and picking a '6' card out of 4 is 4C1.

Picking either of those is 13C1 + 4C1 = 17.

The total number of cards is 52.
