Easy Probability Urgent!: A bag contains 7 red marbles, 6 blue marbles and 4 green marbles. If three marbles are drawn out of the bag, what is the probability, to the nearest 1000th, that all three marbles drawn will be blue?

answer: 1inch=7days  

12inch=12*7=84days

step-by-step explanation:

answer is because 4×10=40

and 98×4= is 392

40,392

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
