Question

Two standard number cubes are thrown simultaneously. What is the probability that the combined result of the two cubes is exactly 7, or that it is less than (but not equal to) 6? Round answer to the nearest thousandth. A. 0.444. B. 0.556. C. 0.667. D. 0.853

Answer 1

1 + 1, 1 + 2, 1 + 3, 1 + 4, 1 + 6,

2 + 1 , 2 + 2, 2 + 3, 2 + 5,

3 + 1, 3 + 2, 3 + 4,

4 + 1, 4 + 3

5 + 2,

6 + 1.

m = 16

Possible outcomes : 6² = 36, n = 36

P ( A ) = 16/ 36 = 0.4444...≈ 0.444

Answer: A ) 0.444

Hope I helped!

Answer 2

Probability = Desired outcomes ( m ) / Possible outcomes ( n )
Desired outcomes:
1 + 1, 1 + 2, 1 + 3, 1 + 4, 1 + 6,
2 + 1 , 2 + 2, 2 + 3, 2 + 5,
3 + 1, 3 + 2, 3 + 4,
4 + 1, 4 + 3
5 + 2,
6 + 1.
m = 16
Possible outcomes : 6² = 36, n = 36
P ( A ) = 16/ 36 = 0.4444...≈ 0.444
Answer: A ) 0.444
