In a pack of cards their are 52 cards.
In 52 cards their are 26 black and 26 red cards.
In one set their are 13 cards (2, 3, 4, 5, 6, 7, 8, 9, 10, jack, queen, king & ace)
(i). P(red king) = no of red king / no of total cards
P(red king) = 2 / 52
= 1 / 26
(ii). P(queen or jack) = (number of queen is 4 + number of jacks are 4)/ total number of cards
P(queen or jack) = (4 + 4) / 52
= 8 / 52
= 2 / 13.
