The Solution:
Given:
We are asked to find the probability of selecting a black cat.
By formula,
[tex]Probability=\frac{number\text{ of required outcomes}}{total\text{ possible outcomes}}[/tex]Thus,
[tex]P(B)=\frac{number\text{ of black cats}}{total\text{ number of cats}}=\frac{7}{11}[/tex]Therefore, the correct answer is 7/11
