Answer:
<u>999,000</u>
Step-by-step explanation:
<u>We need to find the number that is one thousand (1,000) </u><u>less than</u><u> one million (1,000,000).</u>

- <u>999,000</u>
700,000 + 20,000 + 80
there are no exponents
hope this helps

Step-by-step explanation:

Hence the probability that the airline overbooked this flight
=
