2. Refer to a 2008 report that states that 35% of US householdshave at least one high-definition television. Use the binomialdistribution to calculate the probability that exactly 3 of 16randomly selected households will have at least one high-definition television. Compare the result to the answer inproblem 1. Is it close?

We have given that the random variable X that is high-definition television follows Binomial…
