In a simultaneous throw of a pair of dice, find the probability of getting:

(i) 8 as the sum


(ii) a doublet


(iii) a doublet of prime numbers


(iv) a doublet of odd numbers


(v) a sum greater than 9


(vi) an even number on first


(vii) an even number on one and a multiple of 3 on the other


(viii) neither 9 nor 11 as the sum of the numbers on the faces


(ix) a sum less than 6


(x) a sum less than 7


(xi) a sum more than 7


(xii) at least once


(xiii) a number other than 5 n any dice.


(xiv) even number on each die


(xv) 5 as the sum


(xvi) 2 will come up at least once


(xvii) 2 will not come either time

Sample space = 36

(i) n(E) = 5



(ii) n(E) = 6



(iii) n(E) = 3



(iv)


(v)


(vi)


(vii)


(viii) Number of event with sum 9 or 11 = 6


Number of events of not getting a sum of either 9 or 11 = 36 – 6 = 30



(ix)


(x)


(xi)


(xii)


(xiii)
