Let x be a binomial random variable with n = 10 and p = .4 Find the values of


P(x?4)


E(x)=np

I am not even sure where to start, if someone could give me some examples.
Thanks
 
Time out!! If you cannot do the second one, please get out of this class and re-register for pre-algebra.

For the first, p(x>=4) = 1 - [p(0) + p(1) + p(2) + p(3)]
