AleksandrR [38]

Answer:

The union of two event

Step-by-step explanation:

Addition law of probability  define that probability of two event  is total sum of probability of any event subtract the probability of both events

There are two rules  in addition law:

Addition law 1 -  when both event are mutually exclusive, then probability of either event is the sum of each event probability.

P( A or B) = P(A) +P(B)

Addition law 2 -  when both events are non mutually exclusive then there in addition to the individual probability there is some overlap .

P( A or B) = P(A) +P(B) - P(A and B)

a science quiz has eight multiple choice questions with five choices for each. Find the total number of ways to answer the quest
almond37 [142]

Answer:

390625

Step-by-step explanation:

The questions are all independent -- the answer on one question does not limit the number of possible answers on another question.

The quiz has 5 choices for each question, so there are

5\times5\times5\times5\times5\times5\times5\times5 ways to answer the quiz questions.

Notice that this could be written 5^8.  You could say that the number of ways to answer the questions is

number \, of \, choices^{number \, of \, questions}

Use a calculator to find 5^8

Stratified sampling

Samples may be classified as:

Convenient: Sample drawn from a conveniently available pool.

Systematic: Every kth element is taken. For example, you want to survey something on the street, you interview every 5th person, for example.

Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.

Stratified: Also divides the population into groups. However, then only some elements of the group are surveyed.

In this question:

Population divided into groups, and random samples are drawn from the groups. This is a mark of stratified sampling.
