Explanation / Answer

Solution:

total number of units = 120802

( 1 )

probability that the housing unit obtained has four rooms = 23348/120802 = 0.1932

( 2 )

probability that the housing unit obtained has more than four rooms

= (23348+27941+24682+14690+17207)/120802

= 0.8927

( 3 )

probability that the housing unit obtained has one or two rooms = (575+1420)/120802

= 0.0164

( 4 )

probability that the housing unit obtained has fewer than one room = 0/120802= 0.0000

( 5 )

probability that the housing unit obtained has one or more rooms = 120802/120802= 0.1000
