A) \[\frac{5}{6}\]
B) \[\frac{6}{55}\]
C) \[\frac{6}{{{e}^{5}}}\]
D) \[\frac{6}{{{5}^{e}}}\]
Correct Answer: C
Solution :
Required probability \[=P(X=0)+P(X=1)\] \[=\frac{{{e}^{-5}}}{0!}{{5}^{0}}+\frac{{{e}^{-5}}}{1!}{{.5}^{1}}\] \[={{e}^{-5}}+5{{e}^{-5}}=\frac{6}{{{e}^{5}}}\]You need to login to perform this action.
