Final answer:

The probability of a flipped coin landing on heads four times out of six trials is approximately 0.234375 or 23.44%.

Step-by-step explanation:

The probability of a flipped coin landing on heads four times out of six trials can be calculated using the binomial probability formula.

The formula for calculating the probability of getting exactly k successes (in this case, heads) in n trials is:

P(X = k) = C(n, k) * p^k * (1-p)^(n-k)

Where:

  • C(n, k) is the number of combinations of n objects taken k at a time.
  • p is the probability of success (in this case, heads).
  • n is the total number of trials (in this case, 6).

In this case, we want to find the probability of getting exactly 4 heads, so k = 4.

Since the probability of landing on heads is 0.5 for a fair coin, p = 0.5.

Using the formula:

P(X = 4) = C(6, 4) * (0.5)^4 * (1-0.5)^(6-4)

Simplifying the equation:

P(X = 4) = (15) * (0.5)^4 * (0.5)^2

P(X = 4) = 0.234375

Therefore, the probability of a flipped coin landing on heads four times out of six trials is approximately 0.234375 or 23.44%.
