Question

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
