Directions: Study the following information carefully and answer the questions that follow: A bag contains 2 red balls, 3 white balls and 5 pink balls. |
A) \[\frac{1}{13}\]
B) \[\frac{1}{12}\]
C) \[\frac{7}{17}\]
D) \[\frac{3}{16}\]
E) \[\frac{2}{7}\]
Correct Answer: B
Solution :
\[n(S){{=}^{10}}{{C}_{3}}\] \[n(E){{=}^{5}}{{C}_{3}}\] \[\therefore \]\[P(E)=\frac{^{5}{{C}_{3}}}{^{10}{{C}_{3}}}=\frac{10}{120}=\frac{1}{12}\]You need to login to perform this action.
