Explanation / Answer

Expected frequency is calculated as row total * column total / Table total.

Row total for Administration is ( 91 + 40) = 131

Column total for female is (45 + 40 + 6 + 59) = 161

Table total is (68+91+5+61+56+40+6+59) = 386

The expected number of female students majoring in Administration is 131 * 161 / 386

= 54.64
