Step-by-step explanation:
The odds for an event is basically the ratio of the favorable outcomes to the unfavorable outcomes.
Given : The odds of choosing one black ball from an urn are 7 to 13.
i.e. favorable outcomes for getting black ball = 7
i.e. unfavorable outcomes for getting black ball = 13
Now , Total outcomes = favorable outcomes+ unfavorable outcomes
=7+13=20
Then, the probability of getting a black ball![=\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}](/tpl/images/0134/9139/d9931.png)
Hence, the required probability![=\dfrac{7}{20}](/tpl/images/0134/9139/13947.png)
