1. Suppose that the time between arrivals of insect pollinators to a flowering plant is exponentially distributed with parameter = 0.3hr • Find the mean and standard deviation of the waiting time between suc- cessive pollinator arrivals . If a pollinator just left the plant, what is the probability that you will have to wait for more than three hours...

packet from a height of 1,242 meters. Determine the speed the
package reaches at just the moment before touching the surface.
Consider both speed components.
