1 two cards are drawn from an ordinary deck of 52 cards find the probability of each event showing your reasoning carefully
a two aces
Total number of cards= 52 cards
Total number of ways of selecting 2 cards out of 52 cards= 1326 =combin (52,2)
where combin (52,2) stands for selecting 2 out of 52 cards
Total number of aces= 4 aces
Total number of ways of selecting 2 aces out of 4 aces= 6 =combin (4,2)
where combin (4,2) stands for selecting 2 out of 4 aces
Therefore, probability of two aces= 0.004525 or 1/221 =6/1326
Answer: 0.004525 or 1/221
b two red cards
Total number of cards= 52 cards
Total number of ways of selecting 2 cards out of 52 cards= 1326 =combin (52,2)
where combin (52,2) stands for selecting 2 out of 52 cards
Total number of red cards = 26 red cards
Total number of ways of selecting 2 red cards out of 26 red cards = 325 =combin (26,2)
where combin (26,2) stands for selecting 2 ...
