Two number cubes are rolled. What is the probability of rolling a sum of 9 or a sum that is even?
2 answers:
Well I don't know ! Let's figure it out together. Each cube can land in 6 different ways, so the total number of possible results with two cubes is (6 x 6) = 36 . Now we need to figure out how many of those 36 possibilities meet your specifications ... either 9 or any even number. Ways to make 9 : 3 . . . 6 6 . . . 3 4 . . . 5 5 . . . 4 Four ways to make 9. ____________________________ Ways to make an even number: 1 . . . 1 3 . . . 1 1 . . . 3 2 . . . 2 5 . . . 1 1 . . . 5 6 . . . 2 2 . . . 6 6 . . . 4 4 . . . 6 6 . . . 6 Eleven ways to make an even number. _____________________ Total number of ways to succeed = (4 + 11) = 15 ways So the probability of succeeding (rolling 9 or an even number) is 15 / 36 = 5 / 12 = 0.41666... = (41 and 2/3) % .
Two dice are thrown and the only possibilities are rolling 2-12. we are trying to find the probability of rolling a 2,4,6,8,9,10,12 7 out of 11 is the probability of rolling a 9 or an even

Angle 1 and angle 5 are equal so you can set the equations equal to each other. 60 - 2x = 70 - 4x 60 + 2x = 70 2x = 10 x= 5

J
j=agv where a is a constant of proportionality.
j=1 when g=4 and v=5
1=a*4*5
1=20a
a=1/20
a= 0.05
j=0.05gv
When g=10 and v=9,
j=0.05*10*9
j=0.5*9
j=4.5
Answer:
36
Step-by-step explanation:
divide the 72 pieces by 2, you already know that 6 + 6 is 12, and 30 +30 is 60, so add 60 and 12 and you get 72
