Question

Your sock drawer has 4 pairs of pink socks, 2 pairs of white socks, and 7 pairs of black socks. What is the probability that if you choose at random withough replacement you will not choose black socks 2 days in a row? a 1/12b 2/13c 3/8d 5/26

Answer 1

Case: Probability

Method:

To select socks that are not black without replacement,

Since there are a total of 6 pairs that are not black (NB)

`\begin{gathered} Pr(NB) \\ =(6)/(13)*(5)/(12) \\ =(5)/(26) \end{gathered}`

Final answer:

5/26
