Question

sheet for Exam-2: The right half of the worksheet is for the multiple choice answers or single answer the left side of the exam worksheet. Some of the answers require a written answer. or Single VOCABULARY s (2 pts Please match the correct word with its definition. 1. Sample Space a) A numerical measure assigned to an outcome from a random experiment or random survey 2. Independent Events b) All possible outcomes of an experiment or a Survey 3. Expected Value c) A table that assigns probabilities for the possible values of the events of a variable that meet the probability rules. d) When the occurrence of event (A) does not affect the occurrence of event (B) we say A & B are? e) The sum of each of the probabilities multiplied by the assigned value of the random variable is known also as the mean value.

Explanation / Answer

The answer is

1 - b)

2 - d)

3 - e)

Sample space : Suppose we toss two coins then the outcomes HH, HT, TH, TT

So the set of all the outcomes in the experiment is called sample space.

Independent events : Suppose an urn contain white and red balls and we draw a ball from that urn before the next draw we replace it again and then draw the next. In this case the draws are not depend on the previous draws so we say that the evens are not affect each other and it is called as independent events.

Expected Value: formula of Expected value of the frequency distribution is E(X) = sum of values to their probabilities.
