A) \[1/8\]
B) \[1/2\]
C) \[1/4\]
D) \[2/3\]
Correct Answer: C
Solution :
Given, probability of winning a test match \[P(W)=\frac{1}{2}\] \[\therefore \] Probalitiy losing a match \[P(L)=1-\frac{1}{2}=\frac{1}{2}\] Probability that India?s second win occurs at the third day \[=P(L)P(W)P(W)+P(W)P(L)P(W)\] \[=\frac{1}{2}.\frac{1}{2}.\frac{1}{2}+\frac{1}{2}.\frac{1}{2}.\frac{1}{2}\] \[=\frac{1}{8}+\frac{1}{8}=\frac{1}{4}\]You need to login to perform this action.
