Please help! The graph shows the effect of the number of passengers on the number of crashes per 10,000 trips.

A graph titled Crashes by Number of Passengers and Driver Age shows number of passengers with drivers ages 16 to 17 on the horizontal axis and crashes per 10,000 trips on the vertical axis. 0.5 crashes had 0 passengers. 2.5 crashes had 1 passenger. 3.5 crashes had 2 passengers. 6.5 crashes had 3 or more passengers.

About how many times more likely is a 17-year-old driver to crash with three passengers than with one passenger?

about twice as likely
about three times as likely
about four times as likely
about five times as likely
