Question

The king, queen and jack of clubs are removed from a pack of $52$ playing cards. One card is selected at random, find the probability that the card is a king.

Answer 1

Step 1: Finding the favorable and total number of outcomes

In a pack of cards, there are $52$ cards.

On removal of king, queen and jack of clubs the total cards will be $52-3=49$.

The pack of cards contain $1$ card of king for each suit of clubs, spades, hearts and diamonds.

King of clubs has been removed so the number of king cards is $4-1=3$.

Step 2: Finding the probability that the drawn card is a king

The formula for the probability is expressed as,

$Probability=\frac{Numberoffavorableoutcomes}{Totalnumberofoutcomes}$

Substitute number of favorable outcomes as $3$ and total number of outcomes as $49$.

$\therefore P\left(akingcard\right)=\frac{3}{49}$

Hence, the probability of selecting a king card from a pack of $52$ cards from which a king, queen and jack of clubs is removed is $\frac{3}{49}$.
