• ### Binomial distribution question, I think?

On a 100-question true-false test, what are the odds of getting just the first 23 questions correct? Please include in your answer how to do this. (This is not for a class - I'm just curious.)

• ### What is the derivative of the imaginary number i?

I thought of using the definition of the derivative to find it: f'(x)=lim (h->0) (f(x+h)-f(x))/h = lim ((i+h)-i)/h = lim h/h = lim 1 = 1. Is this right? Are there other proofs?

• ### Can anyone break this code?

74-1-85 9-95-8-92-16 16-92-15-E-45-E-R-8 7-95-E-D 17-18-19

74-33 5-8-86 8-7 90-E 15-57-10-T 36-39-78-8-7?

(Some of the letters are already in place. I don't think any of the numbers represent T, R, E, or D; but I could be wrong. The message may have something to do with American History.)
