A teacher places 10 marbles in a bag. 5 blue marbles,
2 red marbles,
3 yellow marbles,
A student draws one marble from the bag, does not replace it, then draws another marble from the bag. What is the probability that the first marble will be red and the second marble will be blue?

3/20  hope it is right

Step-by-step explanation:

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

should have been evaluated with one odd value and one even value. the expressions have equivalent values when . when , the first expression has a value of 3 and the second
