A) 31/35
B) 4/35
C) 8/35
D) None of these
Correct Answer: B
Solution :
[b] Let us divide the players into two pools A and B each containing 4 players. Let \[{{P}_{4}}\] be in pool A. now \[{{P}_{4}}\] will reach the final if we fill the remaining three of pool A by any of \[{{P}_{5}},{{P}_{6}},{{P}_{7}}\,\,or\,\,{{P}_{s}}\]. \[\therefore \] Probability is \[\frac{^{4}{{C}_{3}}}{^{7}{{C}_{3}}}=\frac{4.3.2}{7.6.5}=\frac{4}{35}.\]You need to login to perform this action.
