A) \[\frac{43}{50}\]
B) \[\frac{7}{50}\]
C) \[\frac{15}{22}\]
D) \[\frac{7}{22}\]
Correct Answer: D
Solution :
Probability \[=\left( \frac{7}{10}\times \frac{2}{10} \right)+\left( \frac{7}{10}\times \frac{8}{10}\times \frac{7}{10}\times \frac{2}{10} \right)\] \[+\left( \frac{7}{10}\times \frac{8}{10}\times \frac{7}{10}\times \frac{8}{10}\times \frac{7}{10}\times \frac{2}{10} \right)+..........\infty \] \[=\frac{7}{22}\]You need to login to perform this action.
