Answer: 56
Step-by-step explanation:
Given : A bag contains five red marbles, three green ones, one transparent one, three yellow ones, and three orange ones .
Red marbles = 5
Green marbles = 3
Total marbles red or green = 5+3=8
The number of combinations of n things taking r at a time is given by :-
![C(n;r)=\dfrac{n!}{r!(n-r)!}](https://tex.z-dn.net/?f=C%28n%3Br%29%3D%5Cdfrac%7Bn%21%7D%7Br%21%28n-r%29%21%7D)
Then, the number of possible sets of five marbles are there in which all of them red or green is given by :-
![C(8;5)=\dfrac{8!}{5!(8-5)!}\\\\=\dfrac{8\times7\times6\times5!}{5!3!}\\\\=\dfrac{8\times7\times6}{6}\\\\=8\times7=56](https://tex.z-dn.net/?f=C%288%3B5%29%3D%5Cdfrac%7B8%21%7D%7B5%21%288-5%29%21%7D%5C%5C%5C%5C%3D%5Cdfrac%7B8%5Ctimes7%5Ctimes6%5Ctimes5%21%7D%7B5%213%21%7D%5C%5C%5C%5C%3D%5Cdfrac%7B8%5Ctimes7%5Ctimes6%7D%7B6%7D%5C%5C%5C%5C%3D8%5Ctimes7%3D56)
Now, the number of possible sets of five marbles are there in which all of them red or green = 56
