A company has determined that if a Senior Sales Representative is sent to a client's place of business to demonstrate the product, a sale is produced 90 % of the time. Suppose a random sample of 13 clients is selected for the Senior Sales Representative to demonstrate the product.

Use the binomial probability distribution to find the probability of greater than or equal to 3 of the demonstrations result in sales. Round your answer to the ten thousandths place (four decimal places)
