A) \[\frac{1}{7}\]
B) \[\frac{1}{3}\]
C) \[\frac{3}{7}\]
D) \[\frac{3}{5}\]
Correct Answer: D
Solution :
\[\Delta AGB,\]\[\Delta \,AFC\]and\[\Delta \,AED\]are isosceles \[P=\frac{{}^{7}{{C}_{1}}\times 3}{{}^{7}{{C}_{3}}}=\frac{7\times 3}{\frac{7\times 6\times 5}{3\times 2}}=\frac{3}{5}\]You need to login to perform this action.
