green (3/7)---------green (2/6) (3/7)*(2/6) = 1/7
---------red (4/6) (3/7) *(4/6) = 2/7
red (4/7)-------------green (3/6) (4/7)*(3/6) = 2/7
-------------red (3/6) (4/7)*(3/6) = 2/7
-------------------------
1/7 + 2/7 + 2/7 + 2/7 = 1
The probailities that two are green are: 1/7
The probabilities that one is green and the other is red are:2 /7 + 2/7 = 4/7
The probabilities that two are red are: 2/7

Answer : -6
The common difference of a sequence is the value that changes every time the sequence continues.
In your sequence it is seen that 6 is subtracted from each term in order to get to the next in the sequence.
Answer:
4(-80) = -320
Step-by-step explanation:
His elevation decreased by 80 each hour. Since he was walking for 4 hours, the equation would be
4(-80) = -320.
3 quarts, because 12 is how many cups you have, and there are 4 cups in a quart. 12/4 is 3, so 3 quarts.
