In: Statistics and Probability
Within a large metropolitan area, 20% of the commuters currently
use the public transportation system, whereas the remaining 80%
commute via automobile. The city has recently revitalized and
expanded its public transportation system. It is expected that 6
months from now 30% of those who are now commuting to work via
automobile will switch to public transportation, and 70% will
continue to commute via automobile. At the same time, it is
expected that 90% of those now using public transportation will
commute via automobile and 10% will continue to use public
transportation. In the long run, what percentage of the commuters
will be using public transportation? (Round your answer to the
nearest percent.)
