\[X=x\] | 0 | 1 | 2 | 3 |
\[P(X=x)\] | \[\frac{1}{3}\] | \[\frac{1}{2}\] | 0 | \[\frac{1}{6}\] |
A) \[m={{\sigma }^{2}}=2\]
B) \[m=1,\,\,{{\sigma }^{2}}=2\]
C) \[m={{\sigma }^{2}}=1\]
D) \[m=2,\,\,{{\sigma }^{2}}=1\]
Correct Answer: C
Solution :
Given, distribution is\[X=x\] | 0 | 1 | 2 | 3 |
\[P(X=x)\] | \[\frac{1}{3}\] | \[\frac{1}{2}\] | 0 | \[\frac{1}{6}\] |
