A) \[\frac{1}{2},\,\frac{1}{12}\]
B) \[\frac{1}{6},\,\frac{5}{12}\]
C) \[\frac{5}{6},\,\frac{1}{2}\]
D) None of these
Correct Answer: D
Solution :
We are given that \[n=3,\] \[p=\frac{1}{6},\] \[q=\frac{5}{6}\] Mean \[=np=3\times \frac{1}{6}=\frac{1}{2}\] Variance \[=nqp=3\times \frac{1}{6}\times \frac{5}{6}=\frac{5}{12}.\]You need to login to perform this action.
