\[x\] | -5 | -4 | -3 | -2 | -1 | 0 | 1 | 2 | 3 | 4 | 5 |
\[P(X=x)\] | P | 2p | 3p | 4p | 5p | 7p | 8p | 9p | 10p | 11p | 12p |
A) \[\frac{1}{72}\]
B) \[\frac{3}{73}\]
C) \[\frac{5}{72}\]
D) \[\frac{1}{74}\]
E) \[\frac{1}{73}\]
Correct Answer: A
Solution :
\[\because \] \[p+2p+3p+4p+5p+7p+8p+9p\] \[+10p+11p+12p=1\] \[\Rightarrow \] \[72p=1\] \[\Rightarrow \] \[p=\frac{1}{72}\]You need to login to perform this action.
