Find the probability of randomly selecting a red, then a green marble from a bag of 5 red, 8 green, and 3 blue marbles when (a) you replace the first marble before drawing the second, and (b) you do not replace the first marble. Then, compare the probabilities. Round your answers to four decimal places.

(a)  The probability  is   5/16 * 3/16  =   15 / 256 ≈  .0586

 

(b)  The probability  is  5/16 * 3/15  =   5/16 * 1/5  =  1/16  = .0625
