Answer:
Not independent
Step-by-step explanation:
The number of single bedroom apartments is 90;
The number of single occupants in that 90 is 64;
64/90 or 32/45 is the rate that a single occupant lives in a 1 bedroom apartment.
The number of multiple bedroom apartments is 110;
The number of single occupants in that 110 is 12;
12/110 or 6/55 is the rate that a single occupant lives in a multiple-bedroom apartment.
The rate of single occupants in any type of apartment is 76/200 or 19/50
32/45>19/50>6/55; since the rate of single occupants in 1 bedroom apartments is higher than the rate of single occupants living in any type of apartment and a multiple-room apartment, the event that an apartment has 1 bedroom and 1 occupant is not indepenent.
I'm not sure about the answer, but this is how I would do it, since 15% and $150 are the same based on the question. do let me know if it's right! :)
