Suppose that a timer for video game has a randomly determined length of time after which an enemy appears. the timer is programmed so that the enemy is equally likely to appear any time between .25 minutes and 2.75 minutes after the timer starts.
(a) Draw a density curve model this distribution of random numbers. Be sure to include scales on both axes.
(b) About what percent of the time will an enemy appear between 0.5 minutes and 2 minutes after the timer starts?
(c) Find the 20th percentile of this distribution.
