Answer:
6/7
Step-by-step explanation:
because there are 28 properties in all
4 of them are railroads
but we're not looking for the probability of selecting a railroad, which would be 4/28 or 1/7, but for not selecting a railroad
and 24 of them are not railroads
So the probability of not selecting a railroad is 24/28, which simplified/reduced is 6/7
