Question

A card is drawn at random from a pack of $52$ cards. Find the probability of getting a king or a heart or a red card.

Answer 1

From the data,

n(S)=52

There are 26 cards and there are 2 more kongs

Let E be the event of getting either a red card or a king

then n(E)=26+2=28

$\therefore P\left(E\right)=\frac{n\left(E\right)}{n\left(S\right)}=\frac{28}{52}=\frac{7}{13}$
