Answer:
s = 4
Step-by-step explanation:
3r = 10 + 5s

5s = 20
s = 20 : 5
s = 4
Answer:
The number of ways of selecting a combination of 8 marbles from a bag containing 20 marbles is 125970
Step-by-step explanation:
The number of selecting 8 marbles from a bag of 20 marbles
A combination gives the number of possible order or arrangement in a collection of k items selected from a set of n items

In the question, k = 8, and n = 20
Substituting the values of n and k in the above equation gives;

Therefore, the number of ways of selecting 8 marbles from a bag containing 20 marbles is given by the combination C₂₀, ₈ = 125970.
