One card is drawn from pack of 52 cards, each of the 52cards being equally likely to be drawn. Find the probability that the drawn is 1. Ace. 2. Either red or king. 3. A face card. 4. A red face card

 There 4 Aces In A Pack Of Cards

Hence Probability = 4/52 = 1/13                                                                                                                                                                                   Either Red Or King = 26+4 = 30 (there are 26 red cards and 4 kings but we have to subtract 2 as there two red kings also) = 28

Probability = 28/52 = 7/13

There Are 3 types Of Face Cards(King,Queen And Jack)
each of four type hence total number of cards = 4*3 = 12

probability = 12/52 = 3/13

Red face cards = 12/2 = 6

Probability = 6/52 = 3/26
