Question

You must roll a total of 9 on two number cubes to win the game. Alex must roll a 6. Who is more likely to win the game on the next turn? Explain...

Answer 1

Answer:

There are 36 possible combinations for 2 dices because there are 6 numbers per dice

6 has 5 combinations because you must use 2 dices

1+5

2+4

3+3

4+3

5+1

So Alex has 6/36 or 1/6 chance of getting exactly 6.

While 9 has 4 combinations.

3+6

4+5

5+4

6+3

So you have 4/36 or 1/9 chance of getting exactly 9.

So Alex has a better chance
