Question

a bag contains 6 white marbles and 4 black marbles. a marble is drawn without replacing the first one. what is the probability of drawing a white marble on the first draw, followed by a white marble on the second?

Answer 1

Answer:

4/15

Step-by-step explanation:

6/10 times 4/9=4/15

Answer 2

Answer:

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

2/6 = 1/3 = 0.33 or 33%
