    *Ahem* Mr F edit in red.

    Let A be the random variable number of dayshift workers in sample.

    Let B be the random variable number of swingshift workers in sample.

    Let C be the random variable number of graveyardshift workers in sample.

    Calculate \Pr(A = 0) + \Pr(B = 0) + \Pr(C = 0) - \Pr(A = 0 \cap B = 0) - \Pr(A = 0 \cap C = 0) - \Pr(B = 0 \cap C = 0).
