Answer
$P(at~least~2)=0.0287$
Work Step by Step
$P(fewer~than~2)=P(x\lt2)=P(0)+P(1)=\frac{(0.261\times1)^0}{0!}e^{-0.261\times1}+\frac{(0.261\times1)^1}{1!}e^{-0.261\times1}=\frac{1}{1}e^{-0.261}+\frac{0.261}{1}e^{-0.261}=0.9713$
The probability that Florida will be hit by at least 2 major hurricanes is the complement of the probability that Florida will be hit by fewer than 2 major hurricanes.
Using the Complement Rule (see page 275):
$P(at~least~2)=P(x\geq2)=1-P(x\lt2)=1-0.9713=0.0287$
