Abag contains 4 white, 3 blue, and 6 red marbles. a marble is drawn from the bag, replaced, and another marble is drawn. find the probibility

First find the probability of each color being drawn.

We need to find the total number of marbles first.

4 + 3 + 6 = 13

So everything will be over 13.

Probability of a white marble being drawn -->

Probability of a blue marble being drawn -->

Probability of a red marble being drawn -->

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

Part a :

Part b :

Part c :

Part d :

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
