Problema Solution
Suppose that 33% of people own dogs. If you pick two people at random, what is the probability that they both own a dog?
Answer provided by our tutors
We will assume independence.
p(both own dog) = p(owns dog)*p(owns dog)
p(owns dog) = 0.33
p(both own dog) = 0.33*0.33
p(both own dog) = 0.1089 or 10.89%
