Answer 2

Answer:

1)The probability of choosing a good mango is 10/13

2)The probability of choosing a rotten mango is 9/39

Step-by-step explanation:

1) It is given that 9 rotten mangoes are mixed with 30 good ones, therefore, the total number of outcomes are 30 + 9 = 39.

Now, the number of favourable outcome that a good mango chosen is 30.

Therefore, probability P of choosing a good mango is:

Therefore, probability P of choosing a good mango is:

P=30/39=10/13

Hence, the probability of choosing a good mango is  10/13.

2)It is given that 9 rotten mangoes are mixed with 30 good ones, therefore, the total number of outcomes are 30+9=39.

Now, the number of favourable outcome that a rotten mango chosen is 9.

Therefore, probability P of choosing a rotten mango is:

P=9/39

Hence, the probability of choosing a rotten mango is 9/39.
