Final answer:

To find the probability of selecting exactly three clubs from a standard deck, where the card is replaced after each selection and the experiment is repeated five times, we use the binomial probability formula. The probability is approximately 0.0404, or 4.04%.

Step-by-step explanation:

To find the probability of selecting exactly three clubs from a standard deck, where the card is replaced after each selection and the experiment is repeated five times, we can use the binomial probability formula:

P(X=k) = C(n, k) * p^k * q^(n-k)

where:

  • X is the number of successes (selecting clubs) in n trials
  • P(X=k) is the probability of getting k successes
  • C(n, k) is the number of combinations of n items taken k at a time
  • p is the probability of success on any single trial (the probability of selecting a club from a standard deck is 13/52)
  • q is the probability of failure on any single trial (the probability of not selecting a club, i.e., selecting a non-club card, is 39/52)
  • n is the number of trials (in this case, 5)
  • k is the number of successes we want (in this case, 3)

Plugging the values into the formula, we have:

P(X=3) = C(5, 3) * (13/52)^3 * (39/52)^2

Simplifying the expression and calculating, we find that the probability of selecting exactly three clubs is approximately 0.0404, or 4.04%.
