Solve the following Binomial Problem by utilizing the Binomial Formula and not the Binomial Probability Table. All work has to be shown. In the case of Exxon, Inc. v. State of Alaska, it was noted that 38 percent of the population in the Valdez, Alaska was employed by the Oil Industry. Let us assume that we selected 8 jurors at random from that population. We need to find the probability that exactly 5 jurors are not employed in the Oil...

Let P(t) represent the number of people who, at time t, are infected with a certain disease. Let N denote the total number of people in the population. Assume that the spread of the disease can be modeled by the initial value problem: dP/dt = k(N − P)P, P(0) = P0. At time t = 0, when 100,000 member of a population of 500,000 are known to be infected, medical authorities intervene with medical treatment. As a consequence of this...

Population Growth: Let P(t) be the number of rabbits in the
rabbit population. In the simplest case we can assume the number of
rabbits born at any moment of time is proportional to the number of
rabbits at this moment of time. Mathematically we can write this as
a differential equation:
Here b is the birth rate, i.e. births per time unit per rabbit.
In the model above we ignore deaths and assume resources are
unlimited.
A. Solve the equation...
