What is the probability that the red marble is drawn first and the white marble is drawn second?


A. 1/64


B. 1/56


C. 1/28


D. 1/4

Answer 1

Answer:

B. 1/56

Explanation:

There are 8 different marbles. In the first draw, you have a one out of 8 chance of getting the red. In the second draw, there are 7 marbles remaining, so a one out of 7 chance of drawing a white marble. To find the total probability of drawing the red and then white marble, we multiply the probabilities if each draw.

(1/8)*(1/7)=1/56
