Abag of marbles contains 5 red, 3 blue, 2 green, and 2 yellow marbles. what is the probability that you choose a blue marble and then another blue marble, assuming you replace the first marble?

PART ANSWER:

Hi. I don't know the entire answer but I do know the probability of chosing a blue marble once is 25%.

5 + 3 + 2 + 2 = 12

3/12 or 1/4 = 25% or .25

Sorry I could not fully help.

I’m not entirely sure but I do know that the probability of picking a blue marble is 25%.

Hope this helps!

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
