In an acid$-$base titration, a base or acid is gradually added to the other until they have completely neutralized each other. Since acids and bases are usually colorless $($as are the water and salt produced in the neutralization reaction$),pH$ is measured to monitor the reaction. Suppose that the equivalence point is reached after approximately $323mL$ of a NaOH solution has been added $($enough to react with all the acetic acid present$)$ but that replicates are equally likely to indicate from $294$ to $356mL($exclusive$),$ measured to the nearest $mL.$ Assume that two technicians each conduct titrations independently. What is the probability that the average volume at equivalence from the technicians is $355mL$ or $356?$
