The binomial and Poisson distributions are two different
discrete probability distributions. Explain the differences between
the distributions and provide an example of how they could be used
in your industry or field of study. In replies to peers, discuss
additional differences that have not already been identified and
provide additional examples of how the distributions can be
used.

Each of the following are characteristics of the sampling
distribution of the mean except:
a.
The standard deviation of the sampling distribution of the mean
is referred to as the standard error.

discrete probability distributions
There are 37 different processors on the motherboard of a
controller. 6 of the processors are faulty. It is known that there
are one or more faults on the motherboard. In an attempt to locate
the error, 7 random processors are selected for testing.
tasks
a) Determine the expected number of defective processors. Round
your answer to 2 decimal places.
b) Determine the variance of the number of defective processors.
Round your answer to 4 decimal places....

1. The probability mass function of a discrete random variable X
is defined as p(x) = ax for x = 1, 2, 4, 8 (p(x) =0 for all other
values) then the value of a is?
2. Let X be a discrete random variable with Var(X) =6.0 and
E(X2) = 17.00. Then: E(X) = ?

Answer
First, decide whether the distribution is a discrete probability
distribution, then select the reason for making this decision.
Decide Yes No
Reason Since the probabilities lie inclusively between 0 and 1
and the sum of the probabilities is equal to 1. Since at least one
of the probability values is greater than...
