Question details

Problem 5. Each space shuttle has siz 0-rings and each O-ring fails with probability ea+bt where a 5.085, b--0.1156, and t is the temperature (in degrees Fahrenheit) at the time of the launch of the space shuttle. At the time of the fatal launch of the Challenger, t 31 (a) Let X be the number of failing O-rings at launch temperature 31.F. What type of probability distribution does X have, and what are the values of its parameters? b) What is the probability P(X 1) that at least one O-ring fails?
