An unbiased dice with faces marked 1, 2,3, 4,5 , and 6 is rolled four times. Out of four face values obtained, the probability that the minimum face value is not less than 2 and the maximum face value is not greater than 5 is

  1. A \(16 / 81\)
  2. B \(1 / 81\)
  3. C \(80 / 81\)
  4. D \(65 / 81\)
Verified Solution

Answer & Solution

Correct Answer

(A) \(16 / 81\)

Step-by-step Solution

Detailed explanation

Here, the face value should be 2, 3, 4, 5 . \(P\) (getting a number not less than 2 and not more than 5 in a single throw) \(=\frac{4}{6}=\frac{2}{3}\) \(\therefore\) Required probability \(=\left(\frac{2}{3}\right)^4=\frac{16}{81}\)
