If three unbiased dice are rolled simultaneously then the probability that all the three dice show distinct numbers is

  1. A \(\frac{1}{36}\)
  2. B \(\frac{35}{36}\)
  3. C \(\frac{5}{9}\)
  4. D \(\frac{4}{9}\)
Verified Solution

Answer & Solution

Correct Answer

(C) \(\frac{5}{9}\)

Step-by-step Solution

Detailed explanation

Total number of elements in sample space \[ =6 \times 6 \times 6=216 \] Ways to get different numbers on all 3 dice \[ =6 \times 5 \times 4=120 \] \(\therefore \quad\) Probability \(=\frac{120}{216}=\frac{5}{9}\).
