Question

A card is drawn from a well shuffled pack of $52$ cards. Find the probability of getting either red or king?

Answer 1

No. of cards $=52$

No. of red cards $=\frac{52}{4}$

$=13$

No. of King cards $=4$

No. of red king cards $=2$

$\therefore$ Probability $=\frac{Favourablecases}{samplespace}$

Favourable case= Red cards+Black King cards

$=13+2=15$

Sample space $=52$

Probability $=\frac{15}{25}$
