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 $271mL$ 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 $247$ to $299mL($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 $298mL$ or $299?$
