Question

Ron Draws 16 cards from a standard deck of 52. The deck is made up of equal numbers of four suits - clubs, diamondsm hearts and spades. How many of the cards drawn can Ron expect to be spades?

Answer 1

Let's think-How many different suits are there? Counting, there should be four. So if we divide 52/4, we get 13, the standard number of each card for a deck. So we can justify that 16/4 would show us the spades, which is...?

Answer 2

This is best solved by drawing a probability tree showing all the possible outcomes for each of the 16 draws.
