Hi
What are the chances/probability of 7 of the same numbers coming up 4 times in a row? 5 times in a row? 6 times in a row?

What is generating the numbers? Roulette? Craps? Lottery tickets?

Assuming 00 roulette, (7/38)^x , where x is the number of times in a row.

"To the power of," which means you are multiplying that thing by itself whatever number of times.

That brings up a question: how did ^ become the standard expression for raising to a power? The only place I ever saw that used was in old school line-number BASIC. (FORTRAN uses ** (i.e. 2**3 = 8), and C uses a function (I think it's pow(x, y) in the math library); in fact, in C, ^ means bitwise XOR (so 6^7 would be 00000110 XOR 00000111, which is 00000001, or 1).)

I think that the ^ refers to superscript. I know that in really old texts, presumably that were typeset using a method that did not allow for proper superscripting, I've seen a full upwards arrow used. Since there is no "up arrow" on a standard keyboard, "^" is used instead (it's the head of the arrow, missing the shaft).
It's also used in certain typesetting languages to denote superscript. Eg, in tex, '^' is superscript and '_' is subscript.
