5.72 A foreman has 10 employees from whom he must select 4 to perform a certain undesirable task.

Among the 10 employees, 3 belong to a minority ethnic group. The foreman selected all three minority employees (plus one other) to perform the undesirable task. The members of the minority group then protested to the union steward that they had been discriminated against by the foreman.

The foreman claimed that the selection was completely at random. What do you think?
