 Define the random variable, its distribution, and compute for the variable/measure that is being asked. You can follow the example below

Ex. A large number of insects are expected to be attracted to a certain variety of rose plant. A commercial insecticide is advertised as being 99% effective. Suppose 200 insects infest a rose garden where the insecticide has been applied. What is the probability that none of these insects can survive? Random variable: X – number of dead insects Distribution: X-Bin(200,0.99) Computation: P[X = 200] = (200) + 0.99200 * 0.01° = 0.1340

An oil company conducts a geological study that indicates that an exploratory oil well should have a 20% chance of striking oil. What is the mean number of oil wells that must be drilled if the company wants to have five oil-striking wells?
