Answer
$P(at~least~2)=0.442$
In about 442 of every 1000 5-gram sample, there will be at least 2 insect fragments.
Work Step by Step
The probability that there will be at least 2 insect fragments in a 5-gram sample is the complement of the probability that there will be fewer than 2 insect fragments in a 5-gram sample.
Using the Complement Rule (see page 275):
$P(at~least~2)=P(x\geq2)=1-P(x\lt2)=1-0.558=0.442$
