Question

1. Find the probability of picking a yellow marble and an orange

marble when 2 marbles are picked (without replacement)
from a bag containing 2 yellow and 4 orange marbles

Answer 1

4/15

Explanation:

Probability is the ratio of the number of possible outcome to the number of total outcome.

Given that the bag contains 2 yellow and 4 orange marbles, the probability of picking a

Yellow marble = 2/(2+4) = 2/6

Orange marble = 4/(2+4) = 4/6

The probability of picking a yellow marble and an orange marble without replacement

= 2/6 * 4/5

= 8/30

= 4/15
