<h3>Answer: 2.25</h3>
==================================
Explanation:
Multiply the values in the second and third columns. Do this row by row.
Row1: 3*20 = 60
Row2: 2*12 = 24
Row3: 1*6 = 6
Row4: 0*2 = 0
Add up the products to get 60+24+6+0 = 90
Then divide this by the total frequency 20+12+6+2 = 40 to get 90/40 = 2.25
