A survey was taken to find the number of children in each of 25 families. The relative frequency distribution of the results is shown below. | Number of Children | Relative Frequency | |---|---| | 0 | 12% | | 1 | 20% | | 2 | 28% | | 3 | 24% | | 4 | 12% | | 5 | 4% | What percent of the families have **2 or 3** children?

Read the two relevant rows and add their relative frequencies: $28\% + 24\% = 52\%$. - Trap C ($48\%$) is the result of dropping the $4\%$ somewhere — perhaps from confusing the rows. - Traps A and B pick a single row instead of adding. A quick sanity check: $52\%$ is about half, and visually the *2 children* and *3 children* rows together account for roughly half the table's mass — that matches.
