A brand name has an 80% recognition rate. If the owner of the brand wants to verify that rate by beginning with a small sample of 10 randomly selected consumers, find the probability that exactly brand name. Use the binomial probability formula to find the probability. The probability that exactly 8 of the 10 consumers recognize the brand name is. (Round to three decimal places as needed.) D
