30% a person wear a coloured shirt and black 30%

Answer 2

Answer: Our required percentage is 0.18%.

Step-by-step explanation:

Since we have given that

Percentage of days a person wear white shirt = 30%

Percentage of days a person wear colored shirt = 100-30=60%

Percentage of days he wear black trouser = 30%

We need to find out the percentage of the day the person wear colored shirt and black trouser.

Since they are independent events.

So, Percentage of the days the person wear colored shirt and black trouser is given by

$60\%\times 30\%\\\\=\dfrac{1800}{10000}\\\\=0.18\%$

Hence, our required percentage is 0.18%.
