Question

You roll a die and pick a card of the two-card set with values 6 and 7. How many DIFFERENT sums are possible? Hint: list all with tree diagram and cross out repeated sums

Answer 1

The die is 1 2 3 4 5 or 6

The card is 6 or 7

Possible sums are

card=6) 1+6=7, 2+6=8, 3+6=9, 4+6=10, 5+6=11, 6+6=12,

card=7) 1+7=8, 2+7=9, 3+7=10, 4+7=11, 5+7=12, 6+7=13

We get seven different sums: 7 8 9 10 11 12 13

Answer: 7
