Question

Suppose that 29% of people own dogs. If you pick two people at random, what is the probability that they both own a dog?Give your answer as a decimal (to at least 3 places) or fraction

Answer 1

Given:

29% of people own dogs = 0.29

The probability that both own a dog is given by:

`P=P(owns\text{ dog\rparen}* P(owns\text{ dog\rparen}`

So:

`P=0.29*0.29=0.084`

Answer: 0.084
