The January 1986 mission of the Space Shuttle Challenger was the 25th such shuttle mission. It was unsuccessful due to an explosion
caused by an O-ring seal failure.
(a) According to NASA, the probability of such a failure in a single mission was 1/59,909. Using this value of pand assuming all
missions are independent, calculate the probability of no mission failures in 27 attempts. Then calculate the probability of at least one
mission failure in 27 attempts. (Do not round your intermediate calculation and round your final answers to 4 decimal places.)
P(x = 0)
P(x 2 1)
(b) According to a study conducted for the Air Force, the probability of such a failure in a single mission was 1/35. Recalculate the
probability of no mission failures in 27 attempts and the probability of at least one mission failure in 27 attempts. (Do not round your
intermediate calculation and round your final answers to 4 decimal places.)
P(x = 0)
P(x 21)
