Sample space of two fair fifty sided dice = 50^2 = 2500
Probability of rolling a double = 50/2500 = 1/50
Probability of not rolling a double = 1 - 1/50 = 49/50
Samantha has $100*1.05=$105, and Audrey has $150*1.04=$156. The difference is $156-$105=$51.
The domain of it is d: [1,+infinity) and the range is r: (-infinity,0].
