Answer»

In a simultaneous throw of a pair of dice, find the probability &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

(vii) neither 9 nor 11 as the sum of thenuntbers on the faces

(ix) a sum less than 6

(x) a sum less than 7

(xi) a sum more than 7

(xii) neither a doublet nor a total of 10

(xiii) odd number on the first and 6 on the second

(xiv) a number greater than 4 on each dice

(xv) a total of 9 or 11

(xvi) a total greater than 8.
