Measurement errors from instruments are often modeled using the uniform distribution to determine the range of large public address system, acoustical engineers use a method of triangulation to measure the shock waves sent out by the speakers. the time at which the waves arrive at the sensors must be measured accurately. in this context, a negative error means the signal arrived too early. a positive error means the signal arrived too late. measurement errors in reading these times have a uniform distribution from -0.05 to +0.05 microseconds. (reference: j. peruzzi and e. hilliard, "modeling time delay measurements errors," journal of the acoustical society of america, vol. 75, no. 1, pp. 197 - 201.) what is the probability that such measurements will be in error by
