Answer:
1/3
Step-by-step explanation:
The box has 4 rotten mangoes and 6 good mangoes.
Now probability of selecting one good mango from the box is number of good mangoes by total number of mangoes.
that is P1 = 6 / 10. =3/5
After selecting one good mango, we have 9 mangoes left. 4 are rotten and 5 are good mangoes.
Now probability of selecting one good mango is 5/9.
Thus P2 = 5/9
Total probability P = P1*P2 = (6/10) X (5/9) =30/90
=1/3
