tia_tia [17]

Answer:

$\dfrac{2}{3}.$

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 $=2\times 12 = 24$

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.

$P(\text{Not tinted})=\dfrac{\text{Pairs of contact lenses not tinted}}{\text{Total pairs of contact lenses}}$

$P(\text{Not tinted})=\dfrac{16}{24}$

$P(\text{Not tinted})=\dfrac{2}{3}$

Therefore, the required probability is $\dfrac{2}{3}.$
