Answer:Probability that at least 2 of them have a dog is 0.913.Step-by-step explanation:We are given that according to a survey 60% of people have a dog.

Also, 5 people are selected randomly.

The above situation can be represented through binomial distribution;where, n = number of trials (samples) taken = 5 people

r = number of success

p = probability of success which in our question is probability

that people have a dog, i.e; p = 60%

Let X =

Number of people who have a dogSO, X ~ Binom(n = 5, p = 0.60)Now, probability that at least 2 of them have a dog is given by = P(X2)0.913Therefore, probability that at least 2 of them have a dog is 0.913.
