1 Permutations with Repetition These are the easiest to calculate When a thing has n different types we have n choices each time! For example: choosing 3 of those things, the permutations are: n × n × n (n multiplied 3 times) More generally: choosing r of something that has n different types, the permutations are: n × n × (r times)

Let's draw a tree diagram: The "Two Chicken" cases are highlighted The probabilities for "two chickens" all work out to be 0 147, because we are multiplying two 0 7s and one 0 3 in each case In other words 0 147 = 0 7 × 0 7 × 0 3 Or, using exponents:

You can use the Combinations and Permutations Calculator to work it out (use n=49, r=6, 'No' for Is Order Important? and 'No' for Is Repetition allowed?) The actual calculation is this: 49 C 6 = 49!43! × 6! = 13983816 So how many times do you need to play to win? 1 Week Suppose you play every week The probability of a win after 1 week is:
