There are: 365 days in a year 25 people in a group So whats the chance that for a given group of 25, two people will have the birthdate (not necessarily the same year)? 365 days …………. 25 people …… = 6.8% Something that occurs with 6.8% probability occurs once every 14.6 times

Example 2: Oprah Winfreys Cars There is a lady named Oprah She has a television show She gives away cars to some of her fans But she has a problem She only has ten shows left before she retires But she has 500 cars to give away But being a fair person, she doesnt want to give an additional car to one of her audiences that increase the ratio between the number of persons per car

Example 3: Counting Heads How do we take a census? 1, 2, 3, 4, … HTC Tracts What are they, where are they, how big are they Undercount How to estimate it, whats the potential cost Sampling techniques
