Possible error in Combinations and Permutations exercise 8 hint #127

Open morbidCode opened 2 years ago

morbidCode commented 2 years ago

Hi. I was currently doing exercise 8 of Combinations and Permutations here (https://discrete.openmathbooks.org/dmoi3/sec_counting-combperm.html). The exercise is: "How many anagrams are there of the word “assesses” that start with the letter “a”?" There is a hint: "We just need a string of 7 letters: 4 of one type, 3 of the other." Since “assesses” has 5 ss and 2 es, should the hint be: "We just need a string of 7 letters: 5 of one type, 2 of the other."? Thanks.

Yeah! Nice catch. Thanks for the report. I'll get it fixed soon.
