Answer:

To find the missing number in the table, let's fill in the cell where "Do Not Have Allergies" intersects with "Do Not Have Asthma."

Since the total number of students who do not have allergies is the sum of those who do not have allergies and have asthma (15) and those who do not have allergies and do not have asthma (the missing number), we can calculate the missing number:

46 (Total Do Not Have Allergies) - 15 (Do Not Have Allergies and Have Asthma) = Missing Number

46 - 15 = 31

Therefore, the missing number in the table is 31.
