Answer #1

Expected frequency is for the cell is found as

$\frac{Row \ Total \times \ Column \ Total}{N}$

N = 668

So expected frequency table is given below

	Rock	Pop	Classical
15-25	64.7665	77.8443	65.3892
25-35	68.1916	81.9611	68.8473
35-45	75.0419	90.1946	75.7635

Please give thumbs up if you like the answer.
