Answer :
Answer:
[tex]C\text{ ; }\frac{1}{13}[/tex]Explanation:
We consider each of the pairs as a single unit
The total number of pairs is thus in the drawer is:
[tex]4\text{ + 2 + 7 = 13}[/tex]The probability of picking a pink sock on the first day is: the number of pink pairs divided by the total number of socks
[tex]\frac{4}{13}[/tex]On the second day, there would be 12 pairs left and 3 pairs of pink socks
The probability of picking a pink socks would thus be:
[tex]\frac{3}{12}\text{ = }\frac{1}{4}[/tex]The probability is the product of the probability on the two days
We have that as:
[tex]\frac{1}{4}\times\frac{4}{13}\text{ = }\frac{1}{13}[/tex]
