4) x 1 day work---->1/5
y 1 day work---->1/8
z 1 day work---->1/t (assume)
3(1/5 + 1/8 + 1/t)=1
by solving
1/t = 1/120
t=120
so z alone can do the job in 120 days

sample space==6^3=216
Sum= 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18
Event = 1 3 6 10 15 21 25 27 27 25 21 15 10 6 3 1
now probability of getting sum=10====> 27/216
