I am struggling with several questions any help would be greatly appreciated I just cant seem to figure these out.
1) Two events A and B are mutually exclusive if the probability that A or B occurs is the sum of the probability that A occurs with the probability that B occurs.
2)A correlation coefficient of 0.96 would mean that the values of x increase as the values of y decrease. True or False?
That condition would cause you to have a negative correlation coefficient.
