The probability of drawing a spade or a 3 from a well-shuffled deck of 52 cards is 1752.
False
There are 13 spades and 4 3's in a deck of 52 cards. But one of these is the 3 of spades. Hence, there are only 13 + 4 – 1 = 16 different cards which represent favorable outcomes.
So the probability is 1652 = 413.
