Let’s check out your problem:

Declan's friend Luka claims that he can read minds. To test Luka's abilities, Declan draws 55 cards without replacement from a standard deck of 5252 playing cards. Declan then asks Luka to identify in any order which 55 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 55 cards in any order?

Q. Declan's friend Luka claims that he can read minds. To test Luka's abilities, Declan draws 55 cards without replacement from a standard deck of 5252 playing cards. Declan then asks Luka to identify in any order which 55 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 55 cards in any order?
  1. Calculate Probability First Card: Calculate the probability of Luka guessing the first card correctly.\newlineThere are 5252 cards in total and Luka needs to guess 11 card correctly.\newlineProbability for the first card = 152\frac{1}{52}.
  2. Calculate Probability Second Card: Calculate the probability of Luka guessing the second card correctly.\newlineAfter the first card is drawn, there are 5151 cards left and Luka needs to guess 11 of those correctly.\newlineProbability for the second card = 151\frac{1}{51}.
  3. Calculate Probability Third Card: Calculate the probability of Luka guessing the third card correctly.\newlineNow there are 5050 cards left, and Luka needs to guess another one correctly.\newlineProbability for the third card = 150\frac{1}{50}.
  4. Calculate Probability Fourth Card: Calculate the probability of Luka guessing the fourth card correctly.\newlineWith 4949 cards remaining, Luka guesses one more.\newlineProbability for the fourth card = 149\frac{1}{49}.
  5. Calculate Probability Fifth Card: Calculate the probability of Luka guessing the fifth card correctly.\newlineThere are 4848 cards left, and Luka makes his final guess.\newlineProbability for the fifth card = 148\frac{1}{48}.
  6. Multiply Individual Probabilities: Multiply all the individual probabilities to find the total probability of Luka guessing all 55 cards correctly.\newlineTotal probability = 152×151×150×149×148\frac{1}{52} \times \frac{1}{51} \times \frac{1}{50} \times \frac{1}{49} \times \frac{1}{48}.
