Answer :

Total numbers of elementary events are: 52

Let E be the event of drawing neither a king or a queen


Let A be the event of drawing a king


Then, the numbers of favourable outcomes are: 4


P (king) = P (A) = 4/52


Let B be the event of drawing a queen


Then, the numbers of favourable outcomes are: 4


P (queen) = P (B) = 4/52


Let C be the event of getting either a king or a queen


Then, the numbers of favourable events are: 4 + 4 = 8


P (either king or queen) = P (C) = 4/52 + 4/52 = 8/52 = 2/13


P (neither king or queen) = P (E) = 1- P (C) = 1- 2/13 = 11/ 13
