Question

Two different dice are thrown at the same time. Find the probability of getting :

(iii) a sum of at least 11 

Answer 1

Total number of outcomes when two dice are rolled = 36 

A Sum at least 11

favorable outcomes are: (5,6), (6,5), (6,6) 

Number of favorable outcomes = 3 

P(Sum is at least 11) = `"Number of favourable outcomes "/"Total number of outcomes "` = `3/36 = 1/12`
