Suppose that A tosses a coin which lands heads with probability pA, and B tosses one which lands heads with probability pB. They toss their coins simultaneously over and over again, in a competition to see who gets the 1st head. The one to get the 1st head is the winner, except that a draw results if they get their 1st heads together.

Calculate:

1. P(A wins);

2. P(B wins);

3. P(draw);

4. the distribution of the number of times A and B must.

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.
