Solution

The correct option is B 713
Total no. of outcomes = 52
Number of black cards (Spade+Club) in a pack of '52' cards = 26
Number of 'Kings' in a pack of cards = 4
Number of 'Black Kings' that have already been included in the number of black cards = 2
Number of favourable outcomes =26+42=28

Probability(getting a black or king) =2852=713
