Answer:
see below
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. :)
