The probability of selecting a green marble in one turn is 7/7+3 which is 7/10. For 3 turns, we will do
Check the picture below, so, those red ones are the midpoints you found.

now, that many units are each distance for those "medians", hmmm now, recall that each unit is meant to be 10 meters, so, just multiply each by 10, to get how many meters long each one is.

Answer:
See explanation below
Step-by-step explanation:
If the base of a radical exponent is the same then the following properties hole and x≠ 0
=
Rule 1
Rule 2
Rule 3
The numerator in the expression is
Using rules 1 and 3
The denominator is
Using rules 1 and 3
Therefore the original expression in exponent form is
Using rule 2 we get the final expression as
2/3 - 3/4 = 8/12 - 9/12 = -1/2
5/3 - 1 = 5/3 - 3/3 = 2/3
So the final expression is
