Question

Find the probability of drawing a card from a well shuffled pack such that the drawn card is either a king or a queen

Answer 1

$\sf{Total \ outcomes = 52}$


$\sf{Favourable \ outcomes \ of \ getting \ a \ king \ or \ queen}$
$\sf{= 4 + 4 = 8}$


$\sf{P ( x ) = {\dfrac{Favourable \ outcomes}{Total \ outcomes}}}$


$\sf{P ( getting \ a \ king \ or \ queen ) = {\dfrac{8}{52}} =}$ ${\boxed{\sf{\red{ {\dfrac{2}{13}}}}}}$

Answer 2

HEY YOUR ANSWER IS:-

Total number of cars in a card pack = 52

So total possible outcomes = 52

There are four king in a pack of card and four Queens in a pack of card

Number of king cards + number of Queen cards = 4+4=8

Now , let P(E) be the probability of drawing a card which is either a queen or King from a well shuffled pack of 52 card ,

So ,

P(E) = number of possible outcomes/ total number of outcomes

P(E) = 8/52 = 2/13 .



I hope you have got your answer .....
