You will be asked to reach into the bucket without took mg and select 2 balls. Because the bucket has been shaken thoroughly, you can assume that each individual ball is selected at random with equal likelihood of being chosen. Now, close your eyes! Reach into the bucket, and pick a ball, (dick the red Ptck-A-8all! icon to simulate reaching into the bucket and drawing your ball.) What is the probability of selecting the color of ball that you just selected? (Enter your answer m decimal format and round it to two decimal places.) Don't put your first ball back into the bucket. Now, reach in (again, no peeking!), and pick your second ball, (dick the red Pick-A-Ball! icon to simulate reaching into the bucket and selecting your next ball.) what is the probability of selecting the color of ball that you selected? (Enter the answer in decimal for mat and round it to 2 decimal places)
