Answer: $\bold{b)\quad \dfrac{17}{36}}$

<u>Step-by-step explanation:</u>

$.\quad \dfrac{1}{6}\bigg(2\dfrac{1}{3}-\dfrac{3}{4}\bigg)+\dfrac{5}{24}\\\\\\=\dfrac{1}{6}\bigg(\dfrac{7}{3}-\dfrac{3}{4}\bigg)+\dfrac{5}{24}\\\\\\=\dfrac{1}{6}\bigg(\dfrac{28}{12}-\dfrac{9}{12}\bigg)+\dfrac{5}{24}\\\\\\=\dfrac{1}{6}\bigg(\dfrac{19}{12}\bigg)+\dfrac{5}{24}\\\\\\=\dfrac{19}{72}+\dfrac{5}{24}\\\\\\=\dfrac{19}{72}+\dfrac{15}{72}\\\\\\=\dfrac{34}{72}\\\\\\=\large\boxed{\dfrac{17}{36}}$
