For this question, define the event space: in playing cards, there are 4 suits: hearts, diamonds, spades, clubs. hearts and diamonds are red. spades and clubs are black. if you randomly pick a card from the deck, what is the probability of picking one of the two black suits?

the probability of picking one of the two black suits is 1/2

Step-by-step explanation:

Probability outcome: spades or club = 12 + 12 =26

Event space = 52 (i.e 13 × 4)

Pr(one of the two black suits) = pr(spades) + pr(club)

                                                  = 13 ÷ 52   +  13÷52

                                                   =26÷52

                                                    = 1÷2

Yes you got it correct.
