Question

Probability of getting neither king nor a queen when a card is drawn

Answer 1

no of kings in deck of 52 cards =4
no of queens in deck of 52 cards =4

probablity that card drawn is king =p(king)=4/52

probablity that card drawn is queen =p(queen)=4/52

probablity that a card drawn is either king or queen= p(king) + p(queen)=4/52 + 4/52= 8/52

so, probablity that a card drawn is neither king or queen = 1 - {p(king) + p(queen)}
= 1 - 8/52
= 44/52
= 22/27

i hope it helps...
