One box contains 10 mangoes. 4 of them are rotten and remaining all are good mangoes. 2 mangoes are selected at random. one of them is good one. Find the probability that the second one is also a good one.
Please answer it fastly
HI Swetha,
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.
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) * (5/9)
Please feel free to ask as many questions you have.
