Probability and mutual problems. I need to understand how Q12 to 15. Thanks.

Q.4 12. Find the indicated probability. A bag contains four chips of different colors, including red, blue, green, and yellow. A chip is selected at random from the bag and then replaced in the bag. A second chip is then selected at random. Make a list of the possible outcomes (for example RB represents the outcome red chip followed by blue chip) and use your list to determine the probability that the two chips selected are the same color. (Hint: There are 16 possible outcomes.) 13. Find the indicated probability by using the general addition rule. A lottery game has balls numbered 1 through 19. What is the probability of selecting an even numbered ball or the number 4 ball? 9 14. Find the indicated probability by using the general addition rule. The manager of a bank recorded the amount of time each customer spent waiting in line during peak business hours one Monday. The frequency table below summarizes the results. If we randomly select one of the times represented in the table, what is the probability that it is at least 12 minutes or between 8 and 15 minutes? 0.109 0.455 0.564 0.625 15. Find the indicated probability. If two balanced die are rolled, the possible outcomes can be represented as follows. (1, 1) (2, 1) (3, 1) (4, 1) (5, 1) (6, 1) (1, 2) (2, 2) (3, 2) (4, 2) (5, 2) (6, 2) (1, 3) (2, 3) (3, 3) (4, 3) (5, 3) (6, 3) (1, 4) (2, 4) (3, 4) (4, 4) (5, 4) (6, 4) (1, 5) (2, 5) (3, 5) (4, 5) (5, 5) (6, 5) (1, 6) (2, 6) (3, 6) (4, 6) (5, 6) (6, 6) Determine the probability that the sum of the dice is 2 or 12
