Question

If a pair of dice is thrown.Find the probability that the sum of digits is neither 7 nor 11

Answer 1

Probablity of sum being 7 = 6/36 = 1/6

Probablity of sum being 11 = 2/36 =1/18

Probablity of sum neither 7 nor 11 = 1 -( probability of sum being 7 or 11)

= 1 - (2/9) = 7/9

Therefore Probablity of sum neither 7 nor 11 is 7/9.
