Explanation:

Step1: Find the value of a

To find the value of a, we use the fact that for the "No Laptop" row, the sum of the "No Cell Phone" and "Cell Phone" columns gives the total. So, we subtract the number of people with a cell - phone in the "No Laptop" row from the total of the "No Laptop" row. That is, $a = 207−159$.
$a = 48$

Step2: Find the value of b

To find the value of b, we use the fact that for the "Laptop" row, the sum of the "No Cell Phone" and "Cell Phone" columns gives the total. So, $b=82 + 11$.
$b = 93$

Answer:

The cell labeled a is 48.
The cell labeled b is 93.
