You randomly select one card from a 52-card deck. find the probability of selecting a redred fivefive or a redred fourfour.
2 answers:
P(red 5) = 2/52 = 1/26
P(red 4) = 1/26
P( red 4 OR red 5) = 1/26 + 1/26 = 1/13 answer
There is 2 red fives in a deck ( Hearts and Diamonds) and 2 red fours, for a total of 4 possible cards.
This would give a probability of 4/52, which reduces to a 1/13 probability.
