Answer: The probability of Beth getting selected is [tex]\frac{79}{80}[/tex]
Step-by-step explanation:
Since we have given that
Probability of selecting Jim is given by
[tex]\frac{1}{80}[/tex]
According to question, Jim and Beth are both member of a population.
As we know that ,
[tex]P(Jim)+P(Beth)=1[/tex]
So, using this , we get chances of Beth being selected:
[tex]P(Jim)+P(Beth)=1\\\\\frac{1}{80}+P(Beth)=1\\\\P(Beth)=1-\frac{1}{80}\\\\P(Beth)=\frac{80-1}{80}=\frac{79}{80}[/tex]
Hence, the probability of Beth getting selected is [tex]\frac{79}{80}[/tex]
Answer: 1/80
Step-by-step explanation:
In statistics, a simple random sample is a sample which is a subset of the population the researcher surveyed chosen in a way such that all the individuals in the population has an equal chance to be selected. .
Given: Jim and Beth are both members of a population, and a simple random sample is being conducted.
Then both has equal chances of getting selected.
Thus if the chance of him being selected is 1/80, then the chance of Beth being selected will also be 1/80.
