Question

A card is drawn from a well shuffled deck of $52$ cards. find the probability of getting a king of red colour.

Answer 1

In a pack, there are $52$ cards.

Hence, $n\left(S\right)=52$.

Let A be the event of getting a king of red colour.

In a deck, there are $2$kings of red colour. ($1$ king of diamond and $1$ king of heart).

Hence, $n\left(A\right)=2$

Hence, the probability of getting a king of red colour, $P\left(A\right)=n\left(A\right)/n\left(S\right).$

$P\left(A\right)=2/52$

$P\left(A\right)=1/26.$
