Talking as if the balls do not get put back into the bag, the first probability is 3/10 for yellow. For red it will be 7/9 because there is one less ball (yellow) in the bag.
4.67 would be a rounded answer. Really it's 4.666666666666666666 (the 6 go on forever) but we can't write that out.
Answer:
Considering the average fence size is 4 feet Kara will need 24 fences
Step-by-step explanation:
94/4= 23.5
simplified 24
A=1 and 2
B=2 and 4
C=1,2,7 and 14
D=1,2,4,and 8
Solve for x (isolate/get x by itself)
Add 5 on both sides

Subtract 1/4x on both sides

Make the denominators the same of the fractions in order to combine them. Multiply 2 to the top and bottom of 1/4x

Multiply 8 on both sides

-16 = x
