Answer
$P(at~least~one~of~five~40-year-old~males~will~not~live~to~be~41~years~old)=0.01209$
Work Step by Step
The event "at least one of five randomly selected 40-year-old males will not live to be 41 years old" is the complement of "five randomly selected 40-year-old males will live to be 41 years old". So, we use the Complement Rule (see page 275):
$P(at~least~one~of~five~40-year-old~males~will~not~live~to~be~41~years~old) =$
$=1-P(five~randomly~selected~40-year-old~males~will~live~to~be~41~years~old)=$
$1-0.98791=0.01209$
