Try this:

irb(main):001:0> def random_number(from, to)
irb(main):002:1> from + rand((to - from).abs)
irb(main):003:1> end
=> #<Rubinius::CompiledMethod random_number file=(irb)>
irb(main):004:0> random_number(6, 9)
=> 6
irb(main):005:0> random_number(6, 9)
=> 7
irb(main):006:0> random_number(6, 9)
=> 6
irb(main):007:0> random_number(6, 9)
=> 6
