A bag held 4 black marbles, 2 red marbles, and 6 white marbles. I drew a black marble and did not replace it. What is the probability of drawing a black marble next?

Answer:

P (black marble) =3/11

Explanation:

We need to find the total number of marbles

4 black marbles+ 2 red marbles+ 6 white marbles= 12 marbles

We take away a black marble and throw it away

3 black marbles+ 2 red marbles+ 6 white marbles= 11 marbles

The probability of drawing a black marble is

P (black marble) = black/total

=3/11
