$\dfrac{1}{10}$

Step-by-step explanation:

Given: In basket, we have

4 black socks, 7 pink socks, and 10 white socks.

Total socks = 4+7+10 = 21

Probability that first sock is pink = $\dfrac{\text{Number of pinks socks}}{\text{Total}}=\dfrac{7}{21}=\dfrac13$

Now basket has 6 pink socks left and total socks left= 20

Probability that second sock is pink = $\dfrac{6}{20}=\dfrac{3}{10}$

The probability that Allison will select 2 pink socks = $\dfrac13\times\dfrac{3}{10}=\dfrac{1}{10}$

Hence, the probability that Allison will select 2 pink socks = $\dfrac{1}{10}$
