An urn contains 5 blue balls, 6 red balls, and 7 black balls. Two balls are randomly drawn without replacement.1. What is the probability they are both blue?(Enter as a numerical expression such as 3*2/18 or a decimal accurate to at least 3 decimal places.)2. What is the probability they have different colors?(Enter as a numerical expression such as 3+2/18 or a decimal accurate to at least 3 decimal places.)
