A bag contains 6 red marbles, 2 white marbles, and 1 gray marble. You randomly pick out a marble record it's color, and put it back in the bag. You repeat this process for 45 times. How many white or gray marbles do you expect to get and show me why
You would expect 5. There is one grey marble out of the 9 in total; that can be expressed as 1/9. Since you've repeated it 45 times, it would have been 1/9 45 times, or 1/9(45). I hope I could help!
