Toplam ürün sayısı=1000 Her kümedeki ürün sayısı=20 Küme sayısı= Toplam ürün sayısı/Her kümedeki ürün sayısı Küme sayısı = 5 Yani 50 küme seçilmelidir. Bir ürünün seçilme olasılığını bulmak için, seçilen ürünlerin üretilen toplam ürün sayısına göre oranını dikkate almamız gerekir: Bir ürünün seçilme olasılığı Her kümedeki ürün sayısı/Toplam ürün sayısı. Bir ürünün seçilme olasılığı 20/1000 = 0,02. Yani bir ürünün seçilme olasılığı 0,02 yani %2'dir.

A particular employee arrives at work sometime between 8:00 a.m. and 8:50 a.m. Based on past experience the company has determined that the employee is equally likely to arrive at any time between 8:00 a.m. and 8:50 a.m. Find the probability that the employee will arrive between 8:05 a.m. and 8:40 a.m. Round your answer to four decimal places, if necessary.
