Novay_Z [31]

Answer: 56

Step-by-step explanation:

Given : Number of red marbles = 5

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 :-

^8C_5=\dfrac{8!}{5!(8-5)!}=\dfrac{8\times7\times6\times5!}{5!3!}=56

Hence, the number of sets of five marbles in which all of them red or green=56
