What is the probability that you draw a diamond or a spade from a standard deck of cards?

There are total 52 cards in a pack of cards and 13 each i.e hearts,spades,clubs and diamonds 
so P(diamond)=13/52
and P(spades)=13/52
so probability that you draw a diamond or a spade is P(D)+P(S)=13/52+13/52=1/2

Y’all got to do it all over
