In the small state lottery, three white balls are drawn (at random) from twenty balls numbered 1 through 20, and a blue super ball is drawn (at random) from ten balls numbered 21 through 30. when you buy a ticket, you select three numbers from 1-20 and one number from 21-30. to win the jackpot, the numbers on your ticket must match the three white balls and the super ball. (you don't need to match the white balls in order). if you buy a ticket, what is your probability of winning the jackpot?

17. a researcher measures three variables, x, y, and z for each individual in a sample of n = 20. the pearson correlations for this sample are rxy = 0.6, rxz = 0.4, and ryz = 0.7. a. find the partial correlation between x and y, holding z constant. b. find the partial correlation between x and z, holding y constant. (hint: simply switch the labels for the variables y and z to correspond with the labels in the equation.) gravetter, frederick j. statistics for the behavioral sciences (p. 526). cengage learning. kindle edition.
