A card is drawn from a deck of 52 cards.

Question:

 A card is drawn from a deck of 52 cards. Find the probability of getting a king or a heart or a red card.

Solution:

Given total number of playing cards $=52$ $\therefore \mathrm{n}(\mathrm{S})=52$

Total number of king cards $=4$

Total number of heart cards $=13$

Total number of red cards $=13+13=26$

$\therefore$ Favourable outcomes $=4+13+26-13-2$

$=28$

We know that,

Probability $=\frac{\text { Number of favourable outcomes }}{\text { Total number of outcomes }}$

$\therefore$ Required Probability $=\frac{28}{52}$

$=\frac{7}{13}$

$\therefore$ Required Probability $=\frac{28}{52}$

$=\frac{7}{13}$
