What is the sum of the geometric series?

Essentially this is asking you to sum the first three values of the geometric series that starts with i being 1 and has the rule of ().

Since we must sum the first three geometric values we need to see what the value of i will be for the first three. The sigma notation shows us that the first i will be equal to 1. This means the second i is 2 and the third i is 3.

Knowing this you can plug in the corresponding i values into () and sum it all together

() + () + ()

() + () + ()

() + () + ()

(8) + (2) + ()

10 +

10.5

Step-by-step explanation:

Part A

the probability that a randomly chosen flight arrives on time = number of flights that arrive on time/ total number of flights

Part B

The same as part A but applied for each carrier and then comparing who has the closest number to 1

Part C

total number of flights that arrives on time in PHL/ total number of flights that are on time for all airports

Part D

look for the carrier Hawaiian Airlines (HA) first and then number of flights that arrives on time for HA/ total number of flights HA has

Part E

look for OO and WN in table

add up all flights made ( all airports) for OO and WN

add up all flights on time for OO and WN

divide flights on time by all flights made

Hope this will help you. :)
