Question

A conditional probability is also known as a posterior probability, which is a revision of the prior probability using additional information.

Select one:

True

False

Answer #1

**Posterior Probability :-**

- A posterior probability, in Bayesian statistics, is the revised or updated probability of an event occurring after taking into consideration new information.
- The posterior probability is calculated by updating the prior probability using Bayes' theorem.
- In statistical terms, the posterior probability is the probability of event A occuring given that event B has occured.

**Hence, the answer is TRUE.**

State, with evidence, whether each of the following
claims is true or false:
a. The conditional probability of A, given B, must be
at least as large as the probability of A.
b. An event must be independent of its complement.
c. The probability of A, given B, must be at least
as large as the probability of the intersection of
A and B.
d. The probability of the intersection of two events
cannot exceed the product of their individual...

A consulting firm submitted a bid for a large research project.
The firm’s management initially felt
they had a 50-50 chance of getting the project. However, the agency
to which the bid was submitted
subsequently requested additional information on the bid. Past
experience indicates that for 75% of the
successful bid and 40% of the unsuccessfully bid the agency
requested additional information.
a)
What is the prior probability of the bid being successfully (that
is prior to the request for...

A selection of coin is known to be either fair (with a
probability 0.5 of coming up heads or tails when flipped) or biased
(with a probability 0.75 of tails, 0.25 of heads.) Further. it is
known that 1/10 of the coins are biased. a) You select a coin at
random. What are the prior odds (not probability) that you have
picked a biased coin? b) You select a coin at random and flip it;
you get tails. What are...

The firm's management initially felt they had a 50-50 chance of
getting the project. However, the agency to which the bid was
submitted subsequently requested additional information on the bid.
Past experience indicates that for 77% of the successful bids and

4 fair 10-sided dice are rolled.
(a)
Find the conditional probability that at least one die lands on
3 given that all 4 dice land on different numbers.
(b)
True or False: If X is the sum of the 4 numbers from
one roll, and Y is the maximum of the 4 numbers from one
roll, then X and Y are independent random
variables.

Decide if events A and B are independent using
conditional probability.
(a) Two dice are tossed. Let A = “sum of 8”
and B = “both numbers are even.”
(b) Select a single card from a standard deck. Let
A = “a heart” and B = “an ace.”
(c) A couple have known blood genotypes AB
and BO. Let A = “their child has genotype
BO” and B = “their child has blood type
B.”

TRUE/FALSE and explain An estimate, also known as a sample
statistic, is simply a rule or formula or method that tells us how
to estimate the population parameter of interest from the
information provided by the sample at hand.

Which of the following statements is NOT TRUE for conditional
formation constants? A. Conditional formation constants allow the
view of uncomplexed EDTA as being in only one form, Y4-, in
equilibrium calculations. B. As pH drops the value of a conditional
formation constant increases. C. The value of a conditional
formation constant must be very large to guarantee sharp end points
during titrations. D. Conditional formation constants are pH
depedent.
