Question

A box contains 25 marbles. there are 6 blue, 2 green, 8 red, 1 yellow, and 3 orange marbles. you randomly choose 3 marbles, one after the other. each time, you replace the marble back in the box before choosing the next one. what is the probability that the first marble is green, the second marble is red, and the third marble is blue?

Answer 1

I don't understand your question. You state that a box contains 25 marbles but 6+2+8+1+3= 20!!!
