So...I feel like an idiot.

I'm doing a multi part problem where it appearsI have the second and third part correct, but the first part incorrect, which the next two parts hinge on.

I'm not replicating the problem here, but the kind of problem it is. Can any one school me on how to do this, because I am ready to smack my head with a hammer.

Example: What is the probability that two graduation dates, independently and uniformly distributed are greater than or equal to 40 days apart. Assume 365 days in a year N = infinity

Example 2: What is the probability that two random holidays, independently and uniformly distributed, are greater than or equal to 10 days apart. Assume 365 days in a year

Example 3: What is the probability that two alien people will have egg days (the day they burst from an egg) that are greater than or equal to 30 days apart. Assume a human year of 365 days.

These should all basically be the same problem and if they aren't then its my mistake because I made them up based on the problem that is slowly killing me.

Assume the first date is X, the second is Y so for each problem

absolute value of [X-Y] > selected amount (ie 40, or 10, or 30, etc.)

PS. I have been all over google, and the results being returned are the birthday paradox which is not what I am asking. I'm not asking what is the probability that two people will share the same birthday. Also I ahve been to Khan academy.com to watch videos, Wolframalpha.com, several other statistics forum, looked in my textbook, looked in statistics for dummies, looked in a public health statistics text book, looked in the statistics problem solver, tried to brain think it out.

I came up with an answer ((selected amount - 1) x 2)/365, but I don't think this is right.
