In mathematics, you don't understand things. You just get used to them.

I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.

Re: Bafflers?

The quote doesn't actually go like that, but, anyway... I am not sure how to do a loop like this in Maxima...

Re: Bafflers?

That is the quote exactly. Here it means 3, 120, 14000, they are all the same.

What kind of a loop are you talking about?

Re: Bafflers?

I don't think so. Doesn't really matter, though.

A while loop.

Re: Bafflers?

I don't think so.

I understand why you feel that way. Although you got the correct answer to the smaller 3 die problem the method you used was cumbersome. You even suspected that. That is why you knew that a a bigger problem would be tougher.

But there is a much better method for both problems. The key is to go back to the smaller problem and find a method that does not use all that casework.

Re: Bafflers?

New problem:

A die is rolled 20 times. What is the probability that the maximum value of the faces is 3?

A says) I still think it is:

B says) Nope!

C says) Seems impossible.

D says) I agree.

E says) I got it!

What is you answer?

Hi;

Yes, it just was made from a different method.

Okay, thanks for stopping by.

Re: Bafflers?

Nice problem, by the way.

I think I have seen a similar problem in one of your threads, a long time ago.

Re: Bafflers?

Probably, some of them I like so much that I have to repeat them.

I am going shopping now, see you later. Can't hold out any longer, there is nothing to eat in here.

Yes, lack of food makes one edgy and mistake prone. Too much food, makes one dull and sleepy.

Re: Bafflers?

New problem:

7 poles are erected on a flat piece of land in a line. The first pole is the tallest, with each successive pole being shorter than the one before. The poles are exactly one foot across at the top of the pole. Each pole is positioned so that if it fell over it would not hit the next pole. An ant comes along and climbs up the side of the first pole across the 1 foot top and down the other side. It then travels to the next pole and does the same thing. When it finishes climbing down the last pole it discovers that is has set a new world record for ants of1568 ft travelled. How high are the poles?

A  fact about the poles. They are all integer heights. The poles are 1 foot thick as mentioned before.
