(ii)sum divisible by 5

Sum

Total number of outcomes when two dice are rolled = 36 

Sum divisible by 5

favorable outcomes are: (1,4), (2.3), (3,2), (4,1), (4,6), (5,5), (6,4)

Number of favorable outcomes= 7 

P(Sum divisible by 5) = `"Number of favourable outcomes "/"Total number of outcomes "` = `7/36`
