Explanation:
A standard pack of playing cards has 4 suits. Hearts, Diamonds, Spades and Clubs. Each suit has 13 cards, numbered 1 - 10 and 3 face cards. King, Queen and Jack.
Total cards in a pack
#=4xx13=52# and
#4xx2=8larr" Kings and Jacks"#
#"Probability" ="number of favourable outcomes"/" total number of possible outcomes"# Favourable outcomes = 8 ( King / Jack) and total number of possible outcomes = 52
#rArrP(K orJ)=8/52=2/13#
