Describe why the following is an Independent event using probability language.

In a bag of marbles, the following represents the distributions: 11 Red, 13 Green, 10 Blue, and 11 Yellow. After removing each marble, you replace them.

 

Expert Solution
Step 1

A bag ( 11 red ,13 green , 10 blue , 11 yellow ) 

Total (N) = 11 + 13 + 10 + 11 = 45 marbles 

Independent events : 

Two events are independent if 

P(A and B) = P(A) × P(B) 

Probability = favorable/Total 

Conditional probability  : 

P( A|B ) = P(A and B) / P(B)
