Answer
$P(two~people~randomly~selected~are~left-handed)=0.0169$
$P(at~least~one~is~right-handed)=0.9831$
Work Step by Step
$P(left-handed)=13$% $=0.13$
Now, using the Multiplication Rule (see page 282):
$P(two~people~randomly~selected~are~left-handed)=$
$P(left-handed~and~left-handed)=$
$P(left-handed)\times P(left-handed)=0.13\times0.13=0.0169$
The event at least one is right-handed is the complement of both are left-handed.
Now, using the Complement Rule (see page 275):
$P(at~least~one~is~right-handed)=$
$1-P(both~are~left-handed)=1-0.0169=0.9831$
