a) Find the expected number of errors.
b) Write out the formula for the distribution of errors in a 2000 symbol message.
c) Find the probability of an error-free message.
d) Find the probability of exactly 1 error.
e) Find the probability of at least 1 error.

p=.001, n=2000
a)Expected number of errors=np=2
b)P(k)=2000Ck*.001^k*.999^(2000-k)
c)P(0)=.999^2000
d)P(1)=2000*.001*.999^1999
e)P(k>=1)=1-P(0)
