Question

The SOA approved calculator has a probability of failing during the exam of 0.2%. A cautious actuarial student brings a second calculator to the exam.

If the failure rate of the second calculator is the same and independent of the first, what is the probability of both calculators failing?

Answer #1

Seven boys and 10 girls take an examination, and each student
has probability 0.2 of failing the examination.

b) Given that three students failed the examination, what is the
probability that all 3 are boys?
c) What is the name of the probability distribution you are
using?

A student makes two tests in the same day. The probability of
the first passing is 0.6, the probability of the second passing is
0.8 and the probability of passing both is 0.5. Calculate:
a) Probability that at least one test passes.
b) Probability that no test passes.
c) Are both events independent events? Justify your answer
mathematically.
d) Probability that the second test will pass if the first test has
not been passed.

An exam has three questions. You estimate your probability of
getting the first question right is 0.7, your probability of
getting the second question right is 0.6, and your probability of
getting the third question right is 0.5. Let Y be a random variable
that is the number of questions you get right on the exam. What is
the distribution ofY?

6.8 A device has a constant failure rate of 0.7/year.
(a) What is the probability that the device will fail during the
second year of operation?
(b) If upon failure the device is immediately replaced, what is
the probability that there will be more than one failure in 3 years
of operation?

The principle of redundancy is used when system reliability is
improved through redundant or backup components. Assume that a
student's alarm clock has a 5.7% daily failure rate. Complete
parts (a) through (d) below.
a. What is the probability that the student's alarm clock will
not work on the morning of an important final exam? (Round to
three decimal places as needed.)
b. If the student has two such alarm clocks, what is the
probability that they both fail on...

Consolidated Builders has bid on two large construction
projects. The company president believes that the probability of
winning the first contract (event A) is 0.7, that the probability
of winning the second contract (event B) is 0.6, and that the
probability of winning both contracts is 0.3.
a) Draw Venn diagram that illustrates the relation between A and
B.
b) What is the probability that Consolidated wins at least one
of the contracts?

student's alarm clock will not work on the morning of an important
final exam? nothing (Round to three decimal places as needed.)
b. If the student has two such alarm clocks, what is the
probability that they both...

An undergraduate business student has purchased a laptop
computer for use during exams. This laptop is perfectly reliable
except for two parts: its microchip, which has a failure rate of
one in every twenty hours of operation; and its battery, which has
a failure rate of one in every ten hours of operation. Also, on
average the battery will wear out in five hours, with a standard
deviation of 30 minutes. What maximum battery life should the
manufacturer specify in...
