Step-by-step explanation:
Given that while investigating customer complaints, the customer relations department of Sonic Air found that 15 percent of the flights arrive early and 25 percent arrive on time.
i.e. remaining 60% arrive late.
Overbooked = 65%
Hence not overbooked =

Late or not overbooked = 72%
Late of not overbooked = Late+not overbooked - both
Probability for late and not overbooked = 23% = 0.23
