Answer:
![\dfrac{2}{3}.](https://tex.z-dn.net/?f=%5Cdfrac%7B2%7D%7B3%7D.)
Step-by-step explanation:
It is given that a box contains 2 dozen pairs of contact lenses ,of which 8 pairs are tinted.
1 dozen = 12 units
Total pairs of contact lenses ![=2\times 12 = 24](https://tex.z-dn.net/?f=%3D2%5Ctimes%2012%20%3D%2024)
Tinted pairs of contact lenses = 8
Pairs of contact lenses not tinted = 24 - 8 = 16
If a pair of contact lenses is drawn at random from the box, then we need to find the probability that it is not tinted.
![P(\text{Not tinted})=\dfrac{\text{Pairs of contact lenses not tinted}}{\text{Total pairs of contact lenses}}](https://tex.z-dn.net/?f=P%28%5Ctext%7BNot%20tinted%7D%29%3D%5Cdfrac%7B%5Ctext%7BPairs%20of%20contact%20lenses%20not%20tinted%7D%7D%7B%5Ctext%7BTotal%20pairs%20of%20contact%20lenses%7D%7D)
![P(\text{Not tinted})=\dfrac{16}{24}](https://tex.z-dn.net/?f=P%28%5Ctext%7BNot%20tinted%7D%29%3D%5Cdfrac%7B16%7D%7B24%7D)
![P(\text{Not tinted})=\dfrac{2}{3}](https://tex.z-dn.net/?f=P%28%5Ctext%7BNot%20tinted%7D%29%3D%5Cdfrac%7B2%7D%7B3%7D)
Therefore, the required probability is ![\dfrac{2}{3}.](https://tex.z-dn.net/?f=%5Cdfrac%7B2%7D%7B3%7D.)
