The expected number of women who should express a fear of flying is 104. This is because the variables are independent, so the probability of a woman expressing a fear of flying is the same regardless of her age or education level. The probability of a woman expressing a fear of flying is 0.2, so the expected number of women who should express a fear of flying is 0.2 * 520 = 104.
