According to the Aeronautics and Space Engineering Board the probability of catastrophic failure for solid rocket motors

Question:

According to the Aeronautics and Space Engineering Board the probability of “catastrophic failure” for solid rocket motors is 1/50. Assuming rocket failures are statistically independent, determine the probability that for two solid rocket motors,

a Neither motor will fail.

b. At least one will fail. (Show the Venn diagram.)

c. Exactly one will fail. (Show the Venn diagram.)
