This was on my last stat test. I thought it was pretty easy, but i
still got it wrong. The answer the teacher gives seems illogical,

There are six colors of m and ms in a bag. There is a different
chance of pulling a certain color out at random.

Red: .3
Brown: .3
Yellow: .1
Green: .1
Blue: .1
Orange: .1

If you put an m and m back everytime you take it out. What is the
probability of drawing the same color m and m 2 times in a row.

Cany anyone help?

Hello,

I guess I would start by trying to add the individual
probabilities of drawing 2 reds, 2 browns, 2 yellows,
2 greens, 2 blues, and 2 Orange. The sum of these
probabilities will give you the probability of drawing
2 M&Ms of the same color.

Is this how you proceeded on the exam?

Regards,
