I did not see your reply when I typed this. Thanks!

I found the solution.

num1 = rand(1001)
num2 = 1001 + rand(1001)
number = num1 + rand(num2)

This can return: num1 = 1000, num2 = 1001, number = 2001

Try

module RandomNumberBetweenTwoRandomNumbers
def self.generate max
first = 1 + rand(max - 2);
second = max - rand(max - (first + 1))
between = first + 1 + rand((second - first) - 1)
[first, between, second]
end
end

puts RandomNumberBetweenTwoRandomNumbers::generate 10
puts RandomNumberBetweenTwoRandomNumbers::generate 100
puts RandomNumberBetweenTwoRandomNumbers::generate 1000

# How about something like:

max = 100

low , high = [ rand(max) , rand(max) ].sort

difference = high - low

middle = low + rand(difference).to_i #to_i for if low and high have same
value

puts "low = #{low}"
puts "middle = #{middle}"
puts "high = #{high}"

The problem with your solution is that low and high can be the same
number.
