3. A bag contains 4 white, 3 blue, and 6 red marbles. A marble is drawn from the bag, replaced, and another marble is drawn. Find the probability that
both marbles are red.

PLZ HELP ME!!! ASAP PLZ

Hope this helps! If I could have brainliest I'm trying to rank up.

Step-by-step explanation:

First find the probability of each color being drawn.

We need to find the total number of marbles first.

4 + 3 + 6 = 13

Everything will be over 13.

Probability of a white marble being drawn --> 4/13

Probability of a blue marble being drawn --> 3/13

Probability of a red marble being drawn --> 6/13

Now to find the probabilities of more than one being drawn, we can multiply.

Part A:

6/13*6/13=36/169

Part B:

3/13*3/13=9/169

Part C:

6/13*6/13=18/169

Part D:

7/13*7/13=49/169

Hello,

For the distance formula of 


the order of the coordinates does not matter. This is because  and  are being squared, so whether the difference is negative or positive, in the end the value will be the same as it is being squared (squared values are always positive (ignoring 0)).

Hope this helps!
