Answer:

1. The total number of times two dice are rolled is 12 x 2 = 24 rolls.

The outcomes where the sum is greater than 5 are:

6 (4+2, 5+1, 6+0), 7 (5+2, 6+1), 8 (6+2, 5+3), 9 (6+3), 10 (6+4, 5+5), 11 (6+5), 12 (6+6).

There are 14 outcomes where the sum is greater than 5.

Experimental probability = Number of favorable outcomes / Total number of outcomes

Experimental probability = 14 / 24

Experimental probability = 7 / 12

2. The outcomes where faces with 5 and 6 dots appear are:

5+6, 6+5

There are 2 outcomes where faces with 5 and 6 dots appear.

Experimental probability = Number of favorable outcomes / Total number of outcomes

Experimental probability = 2 / 24

Experimental probability = 1 / 12

3. The outcomes where the sum is an even number are:

4 (2+2), 6 (3+3, 4+2, 2+4), 8 (4+4, 5+3, 3+5, 6+2, 2+6), 10 (5+5, 6+4, 4+6), 12 (6+6).

There are 11 outcomes where the sum is an even number.

Experimental probability = Number of favorable outcomes / Total number of outcomes

Experimental probability = 11 / 24

4. The outcomes where the sum is an odd number are:

3 (1+2, 2+1), 5 (1+4, 4+1, 2+3, 3+2), 7 (1+6, 6+1, 2+5, 5+2, 3+4, 4+3), 9 (6+3, 3+6, 5+4, 4+5), 11 (6+5, 5+6).

There are 13 outcomes where the sum is an odd number.

Experimental probability = Number of favorable outcomes / Total number of outcomes

Experimental probability = 13 / 24

5. The outcomes where the sum is 4 are:

1+3, 2+2, 3+1

There are 3 outcomes where the sum is 4.

Experimental probability = Number of favorable outcomes / Total number of outcomes

Experimental probability = 3 / 24

Experimental probability = 1 / 8
