For the present problem, we can use the following strategy to calculate:
There will be 4 selection of fruits: For the first, you have 5 possibilities to pick an apple, because there are 5 in the bag. For the second round, there will be only 4 possibilities, because it is the total of apples less the one you already picked. Using this way to think, it will be 3 possibilities for the third and 2 for the last selection of fruit. From this, we can say that there are 120 ways to select 4 apples. But because the order you select them will not affect the result, you can exchange them among themselves, the calculation becomes:
[tex]\begin{gathered} N=\frac{5\times4\times3\times2}{4!} \\ N=\frac{120}{24} \\ N=5 \end{gathered}[/tex]It means the answer is D. 5
