To find the expected frequencies, we assume independence of the rows and columns. To get the expected frequency corresponding to the 11 at top left, we look at row total (21) and column total (30), multiply them, and then divide by the overall total (75). So the expected frequency is:

So to complete the expected table, draw up another table similar to that above and having the same row and column totals. For each entry in this table, we simply calculate (row total*column total)/75. The completed table is:Expected Value of Chi-square Test
