Answer:
P (black) = 2/7
Step-by-step explanation:
We need to know the total amount of marbles.
2 red + 3 green + 2 black = 7 marbles
P ( black) = number of black marbles / total marbles
= 2 /7
6 yards = 216 inches
make a proportion and cross multiply:
3/216 = 2/x
*cross multiply*
3x = 216(2)
x = 144 inches or 4 yards
