Let E be the event that a corn crop has an infestation of ear worms, and let B be the event that a corn crop has an infestation of corn borers.
Suppose that P(E) = 0.29, P(B) = 0.1, and P(E and B) = 0.09. Find the probability that a corn crop has no corn borer infestation.
The answer key says that the answer is 0.9 and I cannot figure
out why. I would appreciate any help or explanation,
thanks.
Homework Answers
It's given P(B) = 0.1
B --> event of corn borers.
P(no corn borers) = 1 - P(corn borers) = 1 - P(B) = 1 - 0.1 = 0.9
Hence, 0.9 is the probability that a corn crop has no corn borer infection.
Please comment if any doubt. Thank you.

The Poisson distribution gives the probability for the number of occurrences for a "rare" event. Now, let x be a random variable that represents the waiting time between rare events. Using some mathematics, it can be shown that x has an exponential distribution. Let be a random variable and let o be a constant. Thenis a curve representing the exponential distribution....

1. In this exercise, you will analyze the supply-demand equilibrium of a city under some special simplifying assumptions about land use. The assumptions are: • all dwellings are situated within apartment complexes, • all dwellings must contain exactly 1,500 square feet of floor space, re- gardless of location, and • apartment complexes must contain exactly 15,000 square feet of floor space per square block of land area. These land-use restrictions, which are imposed by a zoning authority, mean that dwelling...
