You randomly draw a marble from a bag of marbles that contains 3 blue marbles, 4 green marbles, and 5 red marbles. what is p(draw a blue marble)? if necessary, round your answer to 2 decimal places

P(blue) = .25

Step-by-step explanation:

We need to know how many marbles in the bag

3 blue marbles+ 4 green marbles+ 5 red marbles = 12 marbles

P ( blue) = blue / total = 3/12 = 1/4 = .25

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
