Document Summary

Statistics 213: mwf 9:00am-9:50am; lecture 01; professor- cindy sun. Combination rule: consider a sample of n elements that need to be selected from a set of n elements without replacement, the resulting different number of outcomes are denoted by (n choose n) or. Example- you are to pick 5 cards randomly from a deck of cards that contains four suits: , , , and the following denominations: ace, 2, 3, 4, 5, 6, 7, 8, 9, and 10. Choose any random 5 cards to make 2 pairs and a singleton to better understand the question. There are 10 denominations and we need to pick 2 to make two pairs: (10 choose 2) There are 4 denominations out of which you pick any two to make one pair, since there are 2 pairs you do make the selection twice: (4 choose 2) * (4 choose 2)
