Answer 2

Answer: Option 'A' is correct.

Explanation:

Since we have given that

Number of people who read paper and under 40 = 4

Number of people who are under 40 = 40

We need to find the probability that a person surveyed gets the news by reading the paper given that he or she is under 40.

We will use "Conditional probability":

P( person read the paper given that he or she is under 40 ) is given by

`\frac{\text{P(read the paper and are under 40}}{\text{P(person who are under 40)}}\\\\=(4)/(40)\\\\=(1)/(10)* 10\\\\=10\%`

Hence, Option 'A' is correct.
