We can select 0 or 1 or 2 or 3 or 4 mangoes(5 ways). Similarly, we can select 0 or 1 or 2 or 3 apples (4 ways) and 0 or 1 or 2 oranges (3 ways). So the number of selections are 5x4x3 = 60. But in these selections, that selection also comes where none of the fruit is selected. Hence, total selections are 60-1=59
