Answer & Explanation
55/221
Explanation:
Prob. of both red = 26C₂/52C₂
Prob. of both kings = 4C₂/52C₂
Since there are also cads which are both red and king, so we will subtract there prob. There are 2 red cards which are kings
Prob. of both red and king = 2C₂/52C₂
So required prob. = 26C₂/52C₂ + 4C₂/52C₂ – 2C₂/52C₂= 55/221
