The data show the total number of medals (gold, silver, and bronze)won by each country
winning at least one gold medal in the Winter Olympics. Suppose that one of the countries
represented is chosen at random and the total numbers of medals won by that country is
noted. $$\begin{array} { l l l l l l l l l } 1 & 2 & 3 & 3 & 4 & 9 & 9 & 11 & 11 \\11 & 14 & 14 & 19 & 22 & 23 & 24 & 25 & 29\end{array}$$ a. List the sample points for this experiment.
b. Find the probability of each sample point.
c. What is the probability that the country won at least 20 total medals?
