Explanation / Answer

solution:-
given p = 0.11 , n = 24
p(x < 3) = p(x = 0)+ p(x = 1)+ p(x = 2)
= 0.0610 + 0.1810 + 0.2572
= 0.4992

-----------------------------------------------------------

given that p = 0.26 , n = 8
p(x ? 4) =p(x = 4)+ p(x = 5) + p(x = 6) + p(x = 7) + p(x = 8)
= 0.0959+0.0270+0.0047+0.0005+0.0000
= 0.1281
