Declan's friend Luka claims that he can read minds. To test Luka's abilities, Declan draws 5 cards without replacement from a standard deck of 52 playing cards. Declan then asks Luka to identify in any order which 5 cards he drew without looking. Assume that Luka has no special abilities and is randomly guessing the cards. What is the probability that Luka correctly identifies all 5 cards in any order?
Q. Declan's friend Luka claims that he can read minds. To test Luka's abilities, Declan draws 5 cards without replacement from a standard deck of 52 playing cards. Declan then asks Luka to identify in any order which 5 cards he drew without looking. Assume that Luka has no special abilities and is randomly guessing the cards. What is the probability that Luka correctly identifies all 5 cards in any order?
Calculate Probability First Card: Calculate the probability of Luka guessing the first card correctly.There are 52 cards in total and Luka needs to guess 1 card correctly.Probability for the first card = 521.
Calculate Probability Second Card: Calculate the probability of Luka guessing the second card correctly.After the first card is drawn, there are 51 cards left and Luka needs to guess 1 of those correctly.Probability for the second card = 511.
Calculate Probability Third Card: Calculate the probability of Luka guessing the third card correctly.Now there are 50 cards left, and Luka needs to guess another one correctly.Probability for the third card = 501.
Calculate Probability Fourth Card: Calculate the probability of Luka guessing the fourth card correctly.With 49 cards remaining, Luka guesses one more.Probability for the fourth card = 491.
Calculate Probability Fifth Card: Calculate the probability of Luka guessing the fifth card correctly.There are 48 cards left, and Luka makes his final guess.Probability for the fifth card = 481.
Multiply Individual Probabilities: Multiply all the individual probabilities to find the total probability of Luka guessing all 5 cards correctly.Total probability = 521×511×501×491×481.
