Answer:
2
Explanation:
The total number of students who play football is given as 40 in the table. We can find the missing number by subtracting the total number of students who play basketball (38) from the total number of students who play football:
Total number of students who play football - Total number of students who play basketball = Missing number
40 - 38 = 2
Therefore, the missing number in the table is 2.
