Answer:
1/8
Step-by-step explanation:
Chance of getting heads: 1/2
Chance of getting orange marble; 1/4
OMG this is so hard to explain.
basically, you have a 1/2 chance of getting Heads. from there, you have to multiply your chance of getting heads by 1/4. This gives us 1/8. We have a 1/8 chance of getting both heads and the orange marble.

These are the charts that you use to solve this.
Hopefully this helped. Good luck!
Step-by-step explanation:
180(n-2)/n=90 ( this is the solution for the 90)
cross multiplying
180n-360=90n
180n-90n=360
90n=360
90n/90=360/90
n=4, the number of sides for the polygon with 90° is 4 sides
Solution for 100°
180(n-2)/n=100
180n-360=100n
180n-100n=360
80n=360
80n/80=360/80
n=4.5
Same applies to the rest 110°,125° ,150°,175°
Do you need a picture of one??
Split it into two equations:
x - 2 = 6
and
-x + 2 = 6
-----------------------------------------------
x - 2 = 6
Add 2 to both sides:
x = 8
-x + 2 = 6
Subtract 2 to both sides:
-x = 4
Multiply -1 to both sides:
x = -4
So x = 8 and x = -4.
