Results from a marijuana drug test study showed 143 subjects with positive test results including 24 false positive results. there were 157 negative results, including 3 false negative results. what is the probability that a randomly selected subject did not use marijuana? round to three decimal places as needed.

0.5933

Step-by-step explanation:

Given that results from a marijuana drug test study showed 143 subjects with positive test results including 24 false positive results. There were 157 negative​ results, including 3 false negative results.

This can be tabulated as follows:

           Used Marijuana     Not used Marijuana     Total

Results

Positive       143-24 =119           24                           143

Negative          3                      154                           157

Total               122                    178                           300

We have to find that probability that a randomly selected subject did not use​ marijuana

Required prob = total people not used/total people

=

me! what did you put for this question?

step-by-step explanation:

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
