melony:
so for like 7(i) 63/ON/10 you wouldn't use it because it cant be done binomially?
thanks sooooo much you're a life saver!! - that clears that topic up for me! god bless u!!

In question 7 i) its already Normal distribution so you dont have to worry abt the C.C (0.5 thing)
I will give you a simple explanation...
If they ask about the prob. of 3 trials from 5 does this event X occur? You would use the binomial as 5C3 x ...x....
But if they ask you the prob of greater than 156 of event X occurs from 200... You could not possibly do 200C156 x...x... + 200C157 x...x... +.... Till 200C200
So thats why we use the continuity correction to approximate it as a Normal Distribution....So tht It would be much easier..So The Continuity correction here would be 15_._ You tell me :D
