  1. A \(\frac{25}{216}\)
  2. B \(\frac{25}{36}\)
  3. C \(\frac{25}{108}\)
  4. D \(\frac{25}{104}\)
Verified Solution

Answer & Solution

Correct Answer

(A) \(\frac{25}{216}\)

Step-by-step Solution

Detailed explanation

\(p = \frac{6}{36} = \frac{1}{6}\) \(P(\text{2 successes}) = C(4, 2) \left(\frac{1}{6}\right)^2 \left(1-\frac{1}{6}\right)^{4-2}\)
