Problem 2. In a certain (hypothetical) communication system we find the received signal at the input to a signal detector is r = ±A+n where +A and -A occur with equal probability and the noise variable n has probability density function p(n) = { n+1, 1-n, 1≤ n ≤ 0, 0

Question
Please help. The previous solution I received here was helpful but I think the part B portion was incorrect.
Problem 2. In a certain (hypothetical) communication system we find the received signal at the input to a signal detector is r = ±A+n where +A and -A occur with equal probability and the noise variable n has probability density function p(n) = { n+1, 1-n, 1≤ n ≤ 0, 0<n<1. We wish to decide on whether +A was sent or -A was sent. a. Determine the smallest value of A that yields a probability of decision error less than or equal to 10-3. b. What is the smallest value of A that would guarantee error free com- munication, i.e., the probability of error is 0.
