Question

A bag contains 6 white marbles and 4 black

marbles. A marble is drawn from the bag
and then a second marble is drawn without
replacing the first one.
What is the probability of drawing a white
marble on the first draw, followed by a black
marble on the second?

Answer 1

0.33 or 33%

Explanation:

6 = white marbles

4 = black marbles

10 = total marbles

6/10 - Pulling white marbles

4/10 - Pulling black marbles

10 - 4 = 6

2/6 - Pulling two white marbles
