Thanks for replies to my thread, I really appreciated it, although the books were a bit 'over my head' for me at that age :) I'm now in university and getting along well. I got help from the book Calculus The Easy Way to get a grip of what it's like. For serious studying, I studied calculus...

While I was looking up about free falling chain problem(the question about a chain falling on to a table), I wondered how it would be if the chain is knotted. What I'm thinking is that if the chain has a knot, would it make much difference? Two questions; 1) Once the knot hits the table...

Warning: That strobe light worked on 110V - I recommend trying a small camera-flash circuit first. A big strobe light can kill you. Thanks. You mean I can be electrocuted? Great///

Brokers don't earn that much money(and I'm not a sales person). Don't know what tv evangelist is. I heard that jobs related to economy requires as much mathematics as physics(or is it just a rumor?) Arms dealer would be great, but I don't have any money to start with. So I prefer being a...

http://www.aaroncake.net/circuits/strobe.asp Maybe not impossible, yes it's certainly possible, but it looks complicated to me. And how those parts cost, I wonder?

You've got to remember lots of things, like names of chemicals, medicines, etc. I won't do it, 'cause I'm not that into medicine. That's why I study physics.

I really do. All my friends know calculus.(or do they? I don't know for sure). Can you suggest a book or a website? I'm 15.

What I want is a method to calculate those : two sets appearing in a line of 50 numbers three sets appearing in a line of 50 numbers four sets appearing in a line of 50 numbers etc. But a solution that can be used in similar situations will help me.

First one has one "set"(I defined the word, think you should know). And second one has two "sets". But if ruling those out simiplify your calculation, think it's OK.

Just curious... How can you make a simple hi-speed camera or a multiple flash making machine(?)? If there is a way, do tell :biggrin:.

10 numbers will be chosen from 1,2,3...6, and they will form a line, like this 1442345662 There are 2 pairs of sets, as underlined above. What I want to find out is the probability of not just only one, but 2 or more sets(2 same numbers being right next to each other) appearing in a line.

Thanks. Another question How can you calculate the probability of 'n' pairs of same numbers being right next to each other?

How can I calculate the probablity of 2 same numbers being right next to each other, when 100 random numbers chosen from '1,2,3... 6' form a line?

... or suggest a formula to calculate?

I think I understand but
