How many total balls are in the bag?

• A. 12
• B. 10
• C. 15
• D. 18

Answer: (B)

Counting the total in a bag means adding up every item across all groups. Each pile or color contributes its count, and the bag’s total is the sum of those counts. In this scenario, adding all the groups gives ten. For example, one group could have four balls and another six, or three and seven, and both add to ten. Totals like twelve, fifteen, or eighteen would require more balls than are present, so they don’t fit the diagram.
