A random sample of n bike helmets manufactured by a certain company is selected. Let X = the number among the n that are flawed. and let p = Pfllawed). Instead ofselecting n : 20 helmets to examine. suppose I examine helmets in succession until I have found r : 3 flawed ones. If the 20th helmet is the third flawed one (so thatthe number of helmets examined that were not flawed is x = 17). what is the mle of ,0? [Answer in terms of r for r and x for x as necessary.) ll r : 3 and x : 13, what is the mle of ,0? (Give answer accurate to 3 decimal places.)
