DICE 1: DICE 2: DICE 3:

1 4 6

1 5 5

1 6 4

2 3 6

2 4 5

2 5 4

2 6 3

3 2 6

3 3 5

3 4 4

3 5 3

3 6 2

SIMILARLY, 6 WAYS, WITH 4 ON DICE 1, 5 WAYS, WITH 5 ON DICE 1, 4 WAYS, WITH 6 ON DICE 1.

SO, TOTAL WAYS = 3+4+5+6+5+4 = 27.

If you're a computer science student, U can also do it using in C as well!! (Yeah I know this is kinda ridiculous, but what the heck)

#include<stdio.h>
#include<conio.h>
#include<conio.h>
int main()
{
int a,b,c,d=0;
system("cls");
for(a=1;a<=6;a++)
{
for(b=1;b<=6;b++)
{
for(c=1;c<=6;c++)
if(a+b+c==11)
{ printf("%d %d %d\n",a,b,c);
d++;
}}}
printf("Hence the total number of pairs is %d",d);
return(0);
}

As Kapil has shown U get the output as 27 Pairs (3+4+5+6+5+4 = 27)!! chk it out yourself!!

cheers!! :)
