Let A,B, and C be the respective events that the first, second, and third drawn orange is good.
Therefore, probability that first drawn orange is good, P(A)=
15
12
The oranges are not replaced.
Therefore, probability of getting second orange good, P(B)=
14
11
Similarly, probability of getting third orange good, P(C)=
13
10
The box is approved for sale if all the three oranges are good.
Thus, probability of getting all the oranges good =
