Answer
$P(at~least~one~American~trusts~organized~religion)=0.62926$
Work Step by Step
$P(none~of~the~5~trust~organized~religion)\approx0.37074$
The event "at least one American trusts organized religion" is the complement of "none of the 5 trust organized religion".
Using the Complement Rule (see page 275):
$P(at~least~one~American~trusts~organized~religion)=1-P(none~of~the~5~trust~organized~religion)=1-0.37074=0.62926$
