Question
The National Aeronautics and Space Administration (NASA) has experienced two disasters. The Challengerexploded over the Atlantic Ocean in 1986, and the Columbia disintegrated on reentry over East Texas in 2003. Based on the first 113 missions, and assuming failures occur at the same rate, consider the next 23 missions.

1.
What is the probability of exactly two failures? (Round mean value to 3 decimal places and final answer to 4 decimal places.)

Probability
2.
What is the probability of no failures? (Round mean value to 3 decimal places and final answer to 4 decimal places.)
