Question

A box contain 150 mangoes of which 90 are good,45 have minor defects and 15 are rotten.what is the probability of not getting the single rotten mangoes in the box?If 10 boxes are purchased,how many rotten mangoes are expected?

Answer 1

1) P(A)=0.9
2) P(B)=150

Answer 2

Answer:

Probability of not getting rotten mangoes $\frac{9}{10}$

150 rotten mangoes are expected.

Step-by-step explanation:

Given : A box contain 150 mangoes of which 90 are good,45 have minor defects and 15 are rotten.

To find : What is the probability of not getting the single rotten mangoes in the box?If 10 boxes are purchased,how many rotten mangoes are expected?

Solution :

Total mangoes in box = 150

Number of rotten mangoes in one box = 15

Therefore,

Probability of getting rotten mangoes

$\frac{15}{150} = \frac{1}{10}$

Then,

Probability of not getting rotten mangoes

$1-\frac{1}{10} = \frac{9}{10}$

In one box number of rotten mangoes are 15

So, if 10 boxes are purchased then number of rotten mangoes expected is

$15\times 10=150$
