Answer:
Probability can be calculated by dividing the number of possible outcomes by the total number of outcomes.
probability=
There are 4 suits each with 13 cards (10 number and 3 face cards)
Total number of cards = 13 x 4 = 52
1. Probability of having a face card:
There are 3 face cards in each suite and there are four suits in total. Thus, total number of face cards = 3 x 4 = 12
Total number of cards in a deck = 52
Probability of drawing a face cards = = 0.231
2. Probability of drawing a red card:
There are two red suits (red suits heart and red diamonds) each having 13 cards. Thus, total number of red cards = 13 x 2 = 26
Total number of cards in a deck = 52
Probability of drawing a red card = = 0.5
3. Probability of drawing a red face card:
There are two red suits (red suits heart and red diamonds) each having 3 face cards. Thus, total number of red cards = 3 x 2 = 6
Total number of cards in a deck = 52
Probability of drawing a red card = = 0.115
