Do you no what an anagram is?
yeah haha sorry since its for math it just means that it wants all of the possible letter combinations, but i don't know how to get it since it has two Y's
Not the answer you are looking for? Search for more explanations.
Okay, so let's start with how many anagrams does the word YEARL have?
okay.. so how many permutations of the pair YY are there?
i mean it's either the first Y first or the second Y first, so you have 2! = 2 permutations.
but would the order of the two Y's matter since they are the same letter?
suppose in this case it does.
Anyway for YEARLY, you have 6 letters, and 2 are a pair. So if my rusty memory is not failing me, the possible number of permutations would be 6!/2!
i meant 2 are repeated.
Vocabulary: Distinguishable Permutation
When we mix the letters around, can we tell the difference between yearly and yearly? That is, since we can't tell if we switch the y's around we don't need to count them as separate anagrams.
Very nice @bahrom7893! Of course you are a 99 aren't you?
