Explanation / Answer

Probability= No of units/ Total number of units

a) The probability= 0.1935

b)The probability of more than four rooms= P(X>4)= 0.6993

c) The probability of that the unit obtained has one or two rooms:P(1)+P(2)= 0.0162

d)The probability that the housing obtained has fewer than one room: P(X<=1)= 0.0043

d)The probability that the housing obtained one or more rooms: P(X>=1) =1
