This exercise looks at how well the Poisson distribution approximates the binomial distribution. Assume that n=389\displaystyle {n}={389} and p=0.003\displaystyle {p}={0.003} for a binomial distribution.

Find the exact probability of one success in 389 trials.
(Report answer accurate to 6 decimal places.)
P(1)=\displaystyle {P}{\left({1}\right)}=

Find the approximate probability of one success in (an interval spanning) 389 trials.
(Report answer accurate to 6 decimal places.)
P(1)=\displaystyle {P}{\left({1}\right)}=

Find the relative difference between the two values.
Recall, the formula
approximationactualactual100%\displaystyle \frac{{\text{approximation}-\text{actual}}}{{\text{actual}}}\cdot{100}\%
(Report answer as a percent accurate to 4 decimal places; you need not type the “%” symbol.)
rel diff = %
