The probability that heads would be obtained 15 or fewer times when this coin is flipped 25 times is 0.370

How to determine the probability?

The given parameters are:

  • Sample size, n = 25
  • Probability of success, p = 0.65
  • Number of success, x ≤ 15

The probability is represented using the following binomial formula

[tex]P(x) = ^nC_x * p^x * (1 - p)^{n - x}[/tex]

Using the above formula, we have:

[tex]P(x \le 15) = 0.370[/tex]

Hence, the probability is 0.370
