Suppose that the probability that a passenger will miss a flight is 0.0931. Airlines do not like flights with empty seats, but it is also not desirable to have overbooked flights because passengers might not find a seat. What is the complementary probability that a passenger will not miss the flight? 
a) 0.0931 
b) 0.9069 
c) 0.9071 
d) 0.1069
