Question

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?

Answer 1

Explanation:

4+6+5=15

15-1=14

2/14

1/7

Answer 2

`\boxed{(2)/(7)}`

Explanation:

Part 1: Finding out total number of marbles

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

`4 + 6 + 5 = 15` 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.

`(4)/(14) = \boxed{(2)/(7)}` or a 28.57% chance of occurrence.
