A jar has 5 marbles 1 of each of the colors red, white blue and yellow. If 4 marbles are removed from the jar. What is the probability that the yellow marble was removed?
Answer: 4/5
Explanation
Let's analyze the problem:
-
Total marbles in the jar: 5 (red, white, blue, yellow, and 1 more color)
-
4 marbles are removed.
-
Find the probability that the yellow marble was removed.
Step 1: Total ways to remove 4 marbles from 5
Total ways=(5/4)=5Step 2: Number of ways to remove 4 marbles, including yellow
To include the yellow marble, we must select the yellow marble and 3 others from the remaining 4 marbles:
Favorable ways=(4/3)=4Step 3: Probability yellow marble is removed
P=Favorable ways/Total ways=4/5
