Two persons A and B throw three unbiased dice one after the another. If A gets the sum 13 , then the probability that B gets higher sum is

Options

  1. A5 216
  2. B4 27
  3. C35 216
  4. D20 216

Correct answer

C. 35 216

Step-by-step solution

Total possible outcomes when 3 dice are thrown are 6^3=216 Outcomes of type (6,6, )=3 4=12 Outcomes of type (6,5, )=3+2 3!=15 Outcomes of type (6,4, )=3 Outcomes of type (5,5, )=3+1=4 and (6,6,6) Probability = 12+15+4+3+1 216 = 35 216 .
