What is the probability of not drawing a blue marble?

3/4

Step-by-step explanation:

There are 12 marbles.  3 are blue.  The probability of drawing a blue marble is:

P = 3/12 = 1/4

So the probability of NOT drawing a blue marble is:

1 - P = 1 - 1/4 = 3/4

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.
