Question

When two six-sided dice are rolled what is the probability that the product of their scores will be greater than six?

Answer 1

Answer:   $\bold{\dfrac{11}{18}}$

Step-by-step explanation:

Think of the products row by row:

11  12  13  14  15  16  - 0 products greater than 6

21 22 23 24 25 26  - 3 products greater than 6

31 32 33 34 35 36  - 4 products greater than 6

41 42 43 44 45 46   - 5 products greater than 6

51 52 53 54 55 56  - 5 products greater than 6

61 62 63 64 65 66  - 5 products greater than 6

$\dfrac{\text{number greater than 6}}{\text{total possible outcomes}}=\dfrac{22}{36}=\dfrac{11}{18}\ when\ reduced$

Answer 2

Answer:

11/18.

Step by.step explanation:

There are 36 possible outcomes when 2 dice are rolled.

Outcomes for a product greater than six are:

2,4  2,5  2,6  3,3  3,4  3,5  3,6  4,2  4,3  4,4  4,5  4,6  5.2 ......5.6 , 6.2 .......6.6.

=  22 ways.

required Probability is 22/36 = 11/18 (answer).
