For binomial distribution with n=8 and p=0.3 find: a) P( x=0) b) P( x<2 ) c) P( x>3 )

Question

For binomial distribution with n=8 and p=0.3 find:

a) P( x=0)

b) P( x<2 )

c) P( x>3 )

Answer 1

Using a TI series calculator the following code was used. Other calculators or programs will have similar code structure and identical answers.

a) bipdf(8,.3,0) = 0.05765

b) bicdf(8,.3,1) = 0.25530

c) 1 - bicdf(8,.3,3) = 0.19410

note: these are exact answers, from binomial distribution., as requested. Calculations using normal approximation will differ.
