In a board game, you roll a die to win or lose points, depending on the outcome. the outcomes follow this probability distribution. number 1 5 2,3,4,6 probability 1/6 1/6 4/6 points 4 6 -5 if a player can only win by accumulating 20 points, which of the following best describes the fairness of the game? a)it's not a fair game because the weighted average is negative. b)it's a fair game because you could win points. c)it's a fair game because you gain more points if you roll a 5 than if you roll any of the negative outcomes. d)it's not a fair game because the weighted average is positive.

the least common denominator is 40

i think the answer is .36

step-by-step explanation:

what i did was only 2.88 divided by 8

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

there are a number of factors that should be analyzed before starting an observational study.

the main four factors are:

i) introduction:   this should be analysed to check whether the purpose of the study is correctly established and the data recorded are appropriate for the study

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.
