Abag has 1 red marble, 4 blue marbles, and 3 green marbles. peter draws a marble randomly from the bag, replaces it, and then draws another marble randomly. what is the probability of drawing 2 blue marbles in a row? explain your answer

I did this my sophmore year in highschool and I'm trying to remember lol. But first you add all the marbles together. 1+4+3. its eight. and since the marble was put back in this makes it an independant event. i believe the answer would be 2/8 considering that there isnt enough numbers to follow through with the equation of (P(a or b)=P(a)xP(b) . P is the probability and a and b are the variabls that represent the events. You would plug in the numbers of the probabilities into the equation, if you think the question calls for it. sorry it may not have been a staright up answer. 

A. dividing 99 by 204 will tell you that 99 out of 204 of the people were females at the action movie.
