In designing an experiment involving a treatment applied to test​ subjects, researchers plan to use a random sample of subjects selected from a pool of available subjects. How many different simple random samples are possible? What is the probability of each simple random sample in this case?

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .

-3.5 is the distance.

i've had this question so choose the one in the absolute value sign.
