Question

A bag contains 4 red marbles,

Answer 1

Answer:

$\boxed{\frac{2}{7}}$

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.

$4 + 6 + 5 = 15$ 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.

$\frac{4}{14} = \boxed{\frac{2}{7}}$ or a 28.57% chance of occurrence.

Answer 2

Step-by-step explanation:

4+6+5=15

15-1=14

2/14

1/7
