If the PPS selection method is used to choose invoices from this population, calculate the probability that Invoice 7 is the first invoice selected. Assume that the random numbers are not ordered from smallest to largest.

Indien die WEG seleksie-proses gebruik word om fakture uit hierdie populasie te selekteer, bereken die waarskynlikheid dat Faktuur 7 eerste geselekteer word. Neem aan dat die ewekansige getalle nie van klein na groot gerangskik word nie.
