Final answer:
The question requires more information about the distribution of houses by the number of bedrooms to precisely identify the number of homes with 4 or more bedrooms among the total of 120 houses.
Step-by-step explanation:
The question involves finding the number of houses in a community that have 4 or more bedrooms. To solve this problem, we need additional information that specifies how many houses fall into each bedroom category (2 bedrooms, 3 bedrooms, and 4+ bedrooms). Without this information, we cannot determine the exact number of houses that have 4 or more bedrooms from the options provided (a) 2, (b) 10, (c) 100, or (d) 20.
