probability of drawing an ace is 4/52=1/13
probability of drawing a spade is 13/52= 1/4
for drawing an ace or a spade card , we have sum the probability of getting an ace and the probability of getting a spade
1/13+1/4= 17/52
but since an ace of spade is common , we subtract 1/52 from the probability,
we get,16/52 = 4/13
