Answer
$P(at~least~one~American~does~not~trust~organized~religion)=0.994168$
Work Step by Step
$P(all~3~trust~organized~religion)=0.005832$
The event "at least one American does not trust organized religion" is the complement of "all 3 trust organized religion".
Using the Complement Rule (see page 275):
$P(at~least~one~American~does~not~trust~organized~religion)=1-P(all~3~trust~organized~religion)=1-0.005832=0.994168$
