Three of these statements explain how this graph distorts the data and gives a false impression about the prices of the airline tickets.

which statement does not explain the distortion?

a.
because the graph does not include $0 to $200, it appears that the difference between the prices is greater than it actually is.

b.
because the bar representing airline b is twice as tall as the bar representing airline a, it appears that the price of the ticket for airline b is twice as much as airline a.

c.
because the bar representing airline c is three times as tall as the bar representing airline a, it appears that the price of the ticket for airline a is one-third the cost of the ticket for airline c.

d.
because the heights of the bars are different, it appears that a ticket on airline c costs $25 more than on airline b, but $50 more than on airline a.

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.

-6 is the correct option from the above given options
