4 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 varietyof rose plant. A commercial insecticide is advertised as being 99% effective.Suppose 200 insects infest a rose garden where the insecticide has beenapplied. What is the probability that none of these insects can survive?Random variable: X – number of dead insectsDistribution: X-Bin(200,0.99)Computation: P[X = 200] = (200) + 0.99200 * 0.01° = 0.1340 According to the theory of genetics, a certain cross of guinea pigs will result inred, black, and white offspring in the ratio 8:4:4. Find the probability that among8 such offspring 5 will be red, 2 black, and 1 white.

Given There are 3 offspring; red, black and white in the ratio 8:4:4

Choose the correct definition of a random variable from the list below. A random variable is one whose values correspond to a scale with a countable number of values. one that occurs in one of two possible states, labeled success and failure. one that is measured to explain changes in the response variable. one whose values describe the outcome of some chance process. O one whose effect in an experiment cannot be distinguished from the effects of other variables.
