A) \[\frac{1}{3}\]
B) \[\frac{9}{15}\]
C) \[\frac{5}{10}\]
D) \[\frac{2}{3}\]
Correct Answer: D
Solution :
| Total number of balls in a bag =3+5 |
| \[\therefore \] Total number of possible outcomes is 15. |
| The number of favourable outcomes of drawing non-black ball is 10. |
| \[\therefore \]Required probability |
| \[=\frac{Number\text{ }of\text{ }favourable\text{ }outcomes}{Total\text{ }number\text{ }of\text{ }possible\text{ }outcomes}=\frac{10}{15}=\frac{2}{3}\] |
