- Assuming U1 and U2 are independent uniform random variables on the interval (0,1), the distribution of the sum S = U1 + U2 is symmetric triangular (the PDF has a symmetric triangular shape with a mean of 1). amzn.to/3rjDOoA (Probability and Statistics with Applications: A Problem Solving Text, by Asimow and Maxwell)

Be careful with calculating the probability with the area of a triangle. Your example works only because the total area of the square = 1
Right. This should be done directly by integration.
