Given :
Three mangoes
Three apples
$ \therefore$ Total fruits = 6
$ \Rightarrow$ Out of 6 fruits 2 fruits can be selected in $ ^6 C_2$ ways
Also 1 apple and 1 mango can be selected in $ ^3C_1 \times ^3C_1=3\times 3 $ ways
Hence the required probability is $ \large\frac{9}{^6C_2}$
$ = \large\frac{9}{15} = \large\frac{3}{5}$
Ans : (A)
