Early Geiger counters would often err when recording the number of radioactive particles emitted. Suppose that the proportion of error is uniformly distributed on the interval [-.2, .4]. (Note: X = .1 implies that the counter recorded 10% more particles than were actually emitted.)
a. Graph the density curve and label all of the appropriate parts.
b. What is the probability that the counter underrecords the number of particles emitted?
