We consider a population of 100 subjects who were tested for 2 illegal drugs, and adopt a denition of probability as a relative frequency of occurrence (proportion). Recall that a relative frequency (or proportion) is frequency or count of how many times event occurs divided by the total number of trials. Use Stat>Tables>Tally Individual Variables to tally variable Drug 1 user. Choose to display counts and percents by checking the appropriate boxes in the menu. Relative frequency is a number between 0 and 1, while percent is a number between 0 and 100. To convert percent to relative frequency, you need to divide percent by 100. 1. How many of the subjects were drug 1 users? 2. If one subject is selected from this population at random, what is the probability that hefshe is a drug 1 user? (Enter a number between 0 and 1)
