Answer: 56
Step-by-step explanation:
Given : Number of red marbles = 5
Number of green marbles = 3
Number of yellow marbles = 3
Number of orange marbles = 3
Number of red and green marbles = 5+3=8
Now the possible number of sets (combinations) of five marbles are there in which all of them red or green will be :-

Hence, the number of sets of five marbles in which all of them red or green=56
It would be 41.5 divided by 5 because a pentagon has 5 sides

15*3 = 45
45*3 = 135
It looks like the common ratio is correct!
