Answer 1

A bag contains 6 clear marbles and 4 red marbles. One marble is drawn from the bag and replaced. A second marble is drawn from the bag and replaced. What is the probability of getting a red marble the first time AND a red marble the second time?

4/25 is the answer

Answer 2

The answer is "4/25".
bag contains 6 clear marbles and 4 red marbles = 6+4=10
chance of red marble = 4/10
4/10=2/5
Now, probability of getting a red marble the first time AND a red marble the second time = (2/5) x (2/5)=4/25
