A bag contains 4 red marbles, 6 white marbles, and 5 blue
marbles. IT a blue marble was
removed from the bag and not
replaced, what is the probability
of then selecting a red marble?

Step-by-step explanation:

Part 1: Finding out total number of marbles

To start, we need to find out how many marbles are in the bag.

marbles

Part 2: Removing blue marble and finding probability

After removing the blue marble and not replacing it, we can then infer that we have 14 marbles remaining.

If we have 4 red marbles in the bag, simply find the ratio of red marbles to the total marbles.

or a 28.57% chance of occurrence.

after simplifying it i got: -36.25 as my answer. hope that !
