Henry rolls 2 number cubes numbered 1 through 6 while playing his favorite board game. He will get a second turn if he rolls a sum that is an even number less than 10. What are Henry's chances of getting a second turn when he rolls the number cubes? 7/18 11/18 5/36 17/36 I got 5/18. I added up the amount of different ways to get 2-8. I found 10. Either the test is wrong or I'm really bad at counting, and I'm not confident enough to count either of them out.

Answer:
Step-by-step explanation:
The sample size n ( total pairs )=36
Pairs having the even sum less than 10 area
(1,3), (3,1), (1,5), (5,1),(3,5),(5,3),
(2,4), (4,2), (2,6),(6,2),
(1,1),(3,3),(2,2),(4,4)
The number of ways to get a sum that is an even number less than 10= 14
The chances of getting a second turn when he rolls the number cubes=
Hence, The chances of getting a second turn when he rolls the number cubes=
First of all, we know that each cube can land in 6 different ways,
so two cubes can land in (6x 6) = 36 different ways.
Now let's check your count. How many ways can you roll a 2, 4, 6, or 8 ?
Cube-A Cube-B
1 1 2
1 3 4
3 1 4
2 2 4
1 5 6
5 1 6
2 4 6
4 2 6
3 3 6
2 6 8
6 2 8
3 5 8
5 3 8
4 4 8
I get 14 ways.
So the probability of success is
(number of successful ways) / (total possible ways) =
(14) / (36) = 7/18 .

s = rθ
where is the arc length
r is the radius
θ is the angle subtended
So,
θ = s/r = 8π / 4.5 = 16π/9
We multiply it with 180/π to convert it to degrees.
(16π/90) (180/π) = 320°
The correct answer
320
