A) \[\frac{1}{3}\]
B) \[\frac{8}{15}\]
C) \[\frac{5}{18}\]
D) \[\frac{2}{3}\]
Correct Answer: C
Solution :
Number of ways of selecting two good mangoes = \[^{6}{{C}_{2}}=15\]. Number of ways that at least one of the two selected mangoes is to be good \[={}^{6}{{C}_{1}}\times {}^{9}{{C}_{1}}=54\] \[\therefore \] Required probability \[=\frac{15}{64}=\frac{5}{18}\].
