thank you so much! this helps to reaffirm that the answer is wrong
Maybe if you use more significant figure of the probability p, you might get the same value as the answer... Try :)
yup i did that and it didn't work out :( the only time i got 0.960 was when i didn't use sampling mean... it can be derived from using a binom distribution of 240 bombs with p=0.56699 and finding P(X<=149)
If is Binomial 240, then it is not "average bombs per plane"...
ya i agree.. that's why your answer helped to reaffirm that!! :)) thank u ~
