If an apartment is selected at random, what is the probability that it is on the 2nd floor or has 3 bedrooms?
Question 1 options:

Answer 1

On the second floor we have 6 apartments, and we have 2 more apartments with 3 bedrooms, so 8/16 apartments are either on the second floor or have 3 bedrooms. 8/16 is the same as 1/2, or 50%
