Careful, there, Studiot....then their analysis is flawed....
Let's see your analysis before you start suggesting that ours is flawed.
Careful, there, Studiot....then their analysis is flawed....
2. How many ways to choose 2 from a set of 24;
@djsfantasiIf however you insist that the characterers are chosen in order of appearance in the password then their analysis is flawed since there are 25 characters available at the instant of choice of the second character.
I know it is. But the onus is on you now to prove it's not.joey, do you think this...
...is a correct analysis in this situation
I don't have to prove anything....
I ... have asserted very little ...
I consider "No" an assertion.Sorry, joeyd, but No.
I am not avoiding it. I believe your question has been answered in many different ways, by three different people.So , joey, you are avoiding my question.
You posed the question. You claimed to know the answer (by outright rejection of mine). You promised an answer "tomorrow". Your answer has yet to be forthcoming. Instead you appeal to authority claiming that you must be correct because a third party (the exam board) is very, very, rarely wrong.I don't have to prove anything.
My solution is NOT dependent on selecting the second vowel before the first consonant. I explicitly enumerated the possible paths in Post #9 and even more explicitly in Post #29. I fully enumerated toy examples in Posts #33 and again in Post #45. I presented a script that fully enumerates the actual problem choosing the characters in order in Post #39. I've offered to upload a file containing all 794,880 legal passwords so that anyone can comb through it and prove it incorrect by doing any one of three things: (1) finding a single entry that is not a legal password, (2) finding a single legal password that is not in the file, or (3) finding a single example of a duplicate entry. I even said that I am willing to put money on the line at 10:1 odds. Why are you ignoring all of these and continue to claim that my solution requires the selection of the second vowel before the first consonant?I understand WBahn's answer and note that joey's working is equivalent,
But I also note that there is a question as to how the password is to be formed.
If you allow the selection of the second vowel before the first consonant WBahn and joey are correct.
If however you insist that the characterers are chosen in order of appearance in the password then their analysis is flawed since there are 25 characters available at the instant of choice of the second character.
This fact is not reflected in joey's permutation expression.
And yes, I have played with a few smaller models to see how things work out, but I am reserving judgement until I have the full information
Forget about the question of whether the problem YOU posted HERE is the same as the original problem posted in some exam review book somewhere. What do YOU claim the correct solution is for the problem YOU posted HERE?So , joey, you are avoiding my question.
I don't have to prove anything.
I posted a problem for discussion, and have asserted very little since there is possibly an issue with the original text.
I certainly do not assert that the solution is 397,440.
However you have asserted that there are only 24 possible choices for the second letter, so prove it.
We are nearing the end of the 2nd day after "tomorrow" and, still, no official answer from the great and powerful messenger of the exam board....answer tomorrow.
I have already said that I have come to the conclusion there must be more to the question that was originally posted and that I am trying to obtain the actual wording of the original to post here.What I don't understand is why studiot can't show us a solution
But it doesn't matter what the original question that was posted somewhere else was! You posted a question HERE and it is THAT question that was asked and it is THAT question that was answered.I have already said that I have come to the conclusion there must be more to the question that was originally posted and that I am trying to obtain the actual wording of the original to post here.
Yes it was and It have already said that way backYou posted a question HERE and it is THAT question that was asked and it is THAT question that was answered.
Actually, looking back I note from your post#8 that you also did a more complete analysis, allowing for the conditional situations.If you allow the selection of the second vowel before the first consonant WBahn and joey are correct.
and I am actively pursuing that possibility at the moment.My answer is correct, or you mis-described the problem.
What are you, some kind of politician?...I'm sure we will all be able to agree on a solution and what went wrong when all the information is collected.
Joey and WBahn, you have an error in the fourth place.
...And yes order does matter...
These affirmative comments were made by you, not the "exam board". Please support them with proper arguments....If however you insist that the characterers are chosen in order of appearance in the password then their analysis is flawed since there are 25 characters available at the instant of choice of the second character.
Has there ever been a rigorous scientific study to determine when "tomorrow" becomes "today"?I'm waiting! Of course, there may be some difficulty in telling the difference between tomorrow and three days later...
My answer is correct, or you mis-described the problem.
Completely irrelevant!...and I am actively pursuing that possibility at the moment.
