Step-by-step explanation:
Step 1: Understanding the possible events
Selecting a chip from Urn I and then adding that chip to Urn II and then selecting a red chip from Urn II can be completed in two ways:
A. Selecting a red chip from Urn I and adding it to Urn II and then selecting a red chip from Urn II
B. Selecting a white chip from Urn I and adding it to Urn II and then selecting a red chip from Urn II
Therefore total probability is:
Step 2: Probability of selecting either chip from Urn I
Urn I contains 2 reds and 4 white chips, that gives a total of 6 chips.
Step 3: Probability of selecting a red chip from Urn II
Urn II originally contains 3 reds and 1 white chip, that gives a total of 4 chips.
Remember: Once a chip is added from Urn I to Urn II the total number of chips will increase in the Urn II
Case 1: When a red chip is added from Urn I to Urn II
Red chips = 4
White chips = 1
Total Chips = 5
Case 2: When a white chip is added from Urn I to Urn II
Red chips = 3
White chips = 2
Total Chips = 5
Therefore the total Probability of selecting a chip from Urn I and then adding that chip to Urn II and then selecting a red chip from Urn II can be calculated as:
