Answer
P(fewer than eight) = $0.844$
If we randomly select 1000 U.S. housing units, we would expect about 844 to be a housing unit that has fewer than eight rooms.
Work Step by Step
The event "a housing unit has fewer than eight rooms" is the complement of the event "a housing unit has eight or more rooms". So:
P(fewer than eight) = 1 - P(eight or more) = $1-0.156=0.844$
