A card is drawn from a deck of 52 cards. Find the probability of getting a king or a heart or a red card.
We know that, in a deck,
Total no. of cards = 52
No. of kings = 4
No. of heart cards = 13
& total no. of red cards = 13 + 13 = 26
Thus, favorable outcomes = 4 + 13 + 26 – 13 – 2
= 28
Now,
Probability = no. of favorable outcomes / total no. of outcomes
= 28 / 52
= 7 / 13
