Explanation
Use the overlapping sets formula for two groups: Total = Group 1 + Group 2 – Both + Neither.
Here, the groups are “stuffed animal” and “given by the baby’s grandmother.” The problem indicates that the “both” category is equal to 5 and that the “neither” number is 6. The total is x.
Total = Group 1 + Group 2 – Both + Neither
x = 9 + 7 – 5 + 6
x = 17
Use the overlapping sets formula for two groups: Total = Group 1 + Group 2 – Both + Neither.
Here, the groups are “stuffed animal” and “given by the baby’s grandmother.” The problem indicates that the “both” category is equal to 5 and that the “neither” number is 6. The total is x.
