The host assigns each passenger a different number. Using a random number table, he draws

50

of those numbers at random. Then, he selects the passengers assigned to the drawn numbers. Every set of

50

passengers is equally likely to be drawn using the random number table.

The host forms groups of

10

passengers based on the passengers' ages. Then, he randomly chooses

5

groups and selects all of the passengers in these groups.

The host forms
