A) 25/169
B) 24/169
C) 49/169
D) 52/169
Correct Answer: A
Solution :
\[P\left( X\text{ }=\text{ }1 \right)\text{ }+\text{ }P\left( X\text{ }=\text{ }2 \right)\] \[=\,\,\,\frac{4}{52}\,\times \,\frac{48}{52}\,\,\times \,\,2\,\,+\,\,\frac{4}{52}\,\,\times \,\,\frac{4}{52}\] \[=\,\,\,\,2\,\,\times \,\,\frac{12}{{{(13)}^{2}}}\,\,+\,\,{{\left( \frac{1}{13} \right)}^{2}}\] \[=\,\,\frac{25}{169}\]You need to login to perform this action.
