banganX 2021-08-18A wildlife biologist examines frogs for a genetic trait he suspects may be linked to sensitivity to industrial toxins in the environment.
Previous research had established that this trait is usually found in 1 of every 8 frogs. He collects and examines a dozen frogs.
If the frequency of the trait has not changed, what’s the probability he finds the trait in
a) none of the 12 frogs?
b) at least 2 frogs?
c) 3 or 4 frogs?
d) no more than 4 frogs?

Yulia 2021-08-17A company with a fleet of 150 vehicles discovered that seven out of the 22 emissions systems they evaluated did not adhere to pollution control standards. Is this conclusive proof that up to 20% of the fleet may not be in compliance? Test a relevant theory, then provide your findings. Before moving on, confirm that all necessary presumptions and criteria have been met.

he298c 2021-08-17A mail-order company advertises that it ships 90% of its orders within three working days.
You select an SRS of 100 of the 5000 orders received in the past week for an audit.
The audit reveals that 86 of these orders were shipped on time.
If the company really ships 90% of its orders on time, what is the probability that the proportion in an SRS of 100 orders is 0.86 or less?

pedzenekO 2021-08-15The game of Clue involves 6 suspects, 6 weapons, and 9 rooms. One of each is randomly chosen and the object of the game is to guess the chosen three. (1) How many solutions are possible? In one version of the game, the selection is made and then each of the players is randomly given three of the remaining cards. Let S, W, and R be, respectively, the numbers of suspects, weapons, and rooms in the set of three cards given to a specified player. Also, let X denote the number of solutions that are possible after that player observes his or her three cards. (2) Express X in terms of S, W, and R. (3) Find E[X]

Chesley 2021-08-14Intrusion detection systems.
A computer intrusion detection system (IDS) is designed to provide an alarm whenever an intrusion (e.g., unauthorized access) is being attempted into a computer system.
A probabilistic evaluation of a system with two independently operating intrusion detection systems (a double IDS) was published in the Journal of
Research of the National Institute of Standards and Technology (Nov.–Dec. 2003).
Consider a double IDS with system A and system B. If there is an intruder, system A sounds
an alarm with probability .9 and system B sounds an alarm
with probability .95.
If there is no intruder, the probability that system A sounds an alarm (i.e., a false alarm) is .2 and the probability that system B sounds an alarm is .1.
Given an intruder, what is the probability that at least one of the systems sounds an alarm?

manufactured chip will have either an etching
or a crack defect (i.e., only one of the two
defects)?
c) What is the probability that a newly
manufactured chip will have neither etching nor
crack defect (i.e., both defects are absent)
d) It is known that a newly manufactured
chip has crack defect. What is the probability

High school probability is one of those interesting tasks that young students receive as part of their statistics and probability assignments. You should also find the answers to probability exercises for high school along with the high school probability questions that will help you come up with the most efficient solutions. If you would like to focus on statistical challenges, you should also use high school probability problems as well as it is based on our examples. Be it related to equations or graphs that will talk about probability, follow our examples and things will become clearer!
