Answer:
The probability that he will choose a Timberland pair at random is;
[tex]P(T)=0.571[/tex]Explanation:
Given that Jordan has 3 pairs of Nike shoes and 4 pairs of Timberland shoes.
[tex]\begin{gathered} n(N)=3 \\ n(T)=4 \\ n(\text{Total)}=3+4=7 \end{gathered}[/tex]The probability of picking a Timberland shoe is;
[tex]\begin{gathered} P(T)=\frac{n(T)}{n(\text{Total)}}=\frac{4}{7} \\ P(T)=0.571 \end{gathered}[/tex]Therefore, the probability that he will choose a Timberland pair at random is;
[tex]P(T)=0.571[/tex]
