A bag contains five blue marbles, five red marbles, five white marbles, and five black marbles. You draw a marble from the bag, and then draw another marble from the bag. Do you have a greater probability of drawing two blue marbles if you replace the first marble after you draw it or if you don't replace the marble?

Your answer should include both the mathematical proof and a written statement.

hey! i think i know the answer haha.

3x-x+2=4. hope that helps!

Step-by-step explanation:

20 marbles in all of which: 5 are blue, 5 are red, 5 are white and 5 are black.Drawing 2 marbles without replacin the 1st blue drawn.

P(2 blue) = 5/20*4/19 = 20/380 = 1/19.Drawing 2 marbles with replacement of the first blue one

P(2 blue) = 5/20*5/20 = 25/400 = 1//16. 1/16 > 1/19
