The value of $e^{-3}$ can be found by using a calculator or by using the identity $e^{-x}=\frac{1}{e^x}$.
Using a calculator, we get $e^{-3}\approx0.0498$.
Using the identity, we have $e^{-3}=\frac{1}{e^3}=\frac{1}{20.0855}\approx 0.0498$.
Therefore, the best choice is $\boxed{	extbf{(B)}\ 0.0498}$.

e−3=e ^ { - 3 } =e−3= A)201 B)0

$e ^ { - 3 } =$ A)201
B)0
