 Question 535579: The question is: You have 9 male and 7 females to choose from to form a team of 6. What is the probability of choosing either all males, or all females. I think I should use nPr formula, but the given answer in the tutorial was 14/(p)*(d) If I use nPr, I get: P = 0.01049 for all male P = 0.000874 for all femaleAnswer by fcabanski(874)   (Show Source): You can put this solution on YOUR website!#1 you're reading the question incorrectly. It isn't two separate questions (a. Find the probability of all males. B. Find the probability of all females). It's a compound question asking you to find the probability that it's all males or all females. Not sure what the answer in the tutorial means. What is p and d? This is the P(male) OR P(Female) = P(Male)+P(Female). These are found with combinations, because order doesn't matter. If the team has Jerry as the first member, or Jerry as the last member, the team still has Jerry. 9C6/16C6 + 7C6/16C6. Check my profile and contact me for one on one online tutoring.
