Question 1196847
<br>
Total number of possible outcomes: 6 possible outcomes on each die, so 6*6 = 36.<br>
Ways to get a 9: 6+3, 5+4, 4+5, 3+6.  (4)<br>
Ways to get doubles: 1+1, 2+2, 3+3, 4+4, 5+5, 6+6.  (6)<br>
Basic definition of probability: (# of good outcomes) divided by (total # of possible outcomes)<br>
ANSWERS:
P(9) = 4/36 = 1/9
P(doubles) = 6/36 = 1/6<br>
