Russ has Card 4.
Step 1
Find out how many combinations there are for each card.
Make a list.

3 
4 
7 
11 
Possible combinations 
1 + 2 2 + 1 
1 + 3 3 + 1 2 + 2

3 + 4 4 + 3 5 + 2 2 + 5 1 + 6 6 + 1 
5 + 6 6 + 5 
Total number of combinations 
2 
3 
6 
2 
Step 2
Find out the total number of possible outcomes using 2 cubes.
6 6 = 36
There are 36 possible combinations.
Step 3
Find out the probability of getting each one of the numbers on the cards.
Use a ratio to find each probability.
combinations possible for each card = 
outcomes in event 
36 
possible outcomes 
Step 4
Use the clues.
 Anna has the greatest probability of scoring a point on her first turn. She must have Card 7 because it has the probability of 6 out of 36.
 Jeff's and Daisy's cards have the same probability. They must have Cards 3 and 11 because the probability of scoring a point with those cards is 2 out of 36.
 Jeff's card has a higher number than Daisy's. He must have Card 11.
 The probability of Russ's earning a point is greater than that of Jeff's earning a point. He must have Card 4 because the probability of that card is 3 out of 36.
Summary
