Question 1174512: In a certain communications system, there is an average of 1 transmission error per 10 seconds Let the distribution of transmission errors, say X be a Poisson distribution. What is the probe ability of more than 1 error in a communication half minute in duration?
Answer by Boreal(15235) (Show Source): You can put this solution on YOUR website!
The errors are proportional to time, so would expect the half-minute distribution to be Poisson with lambda=3.
probability of 0 and 1 are
p(0)=e^(-3)^3^0/0!=0.0498
p(1)=e^(-3)*3^1/1!=0.1494
that sum is 0.1992
the probability of more than 1 is the complement or 0.8008
