The survey by The Bureau of Labor Statistics American Time, showed that the time a person spends in the United States using a computer for entertainment varies greatly according to age. Individuals aged 75 years and older averaged 0.3 hrs (18 minutes) per day. Those aged 15 to 19 spent 1.0 hrs a day. If these times follow an exponential distribution find the proportion of each group that passes:
a) Less than 15 minutes a day using the computer to
entertainment
b) More than two hours
c) Between 30 and 90 minutes
