A bag contains 11 Blue balls, 9 Red balls, and 10 Green balls. Two balls are going to be drawn from the bag (one at a time) and then returned to the bag before the next is drawn. Let event B = blue ball chosen, R = Red ball chosen, and G- Green ball chosen. What is the probability the first is blue and the second is red? What is P(B and then R)? Write an answer to 4 decimal places.
A bag contains 10 Blue balls, 10 Red balls, and 9 Green balls. Two balls are going to be drawn from the bag (one at a time) and then put to the side (they are not returned to the bag). Let event B blue ball chosen, R = Red ball chosen, and G- Green ball chosen. What is the probability they are both red? What is P(R and R)? Write an answer to 4 decimal places.
