Let's tackle the problem step-by-step.

Part A: List of all possible outcomes

The spinner has four sections: water (W), milk (M), tea (T), and lemonade (L). Erin spins the spinner three times, so we need to list all the possible outcomes for three days of drink selections.

Each day has 4 possibilities, so the total number of combinations is $4^3 = 64$.

The list of all possible outcomes (each combination of three spins) is:

WWW, WWM, WWT, WWL, WMW, WMM, WMT, WML, WTW, WTM, WTT, WTL, WLW, WLM, WLT, WLL,
MWW, MWM, MWT, MWL, MMW, MMM, MMT, MML, MTW, MTM, MTT, MTL, MLW, MLM, MLT, MLL,
TWW, TWM, TWT, TWL, TMW, TMM, TMT, TML, TTW, TTM, TTT, TTL, TLW, TLM, TLT, TLL,
LWW, LWM, LWT, LWL, LMW, LMM, LMT, LML, LTW, LTM, LTT, LTL, LLW, LLM, LLT, LLL

Part B: Number of possible outcomes

As calculated, there are $4^3 = 64$ possible outcomes.

Part C: Probability that Erin drinks lemonade one day, tea one day, and water one day

To find this probability, we need to count how many of the outcomes contain exactly one L, one T, and one W, and then divide by the total number of outcomes.

First, let's count the favorable outcomes: The combinations that include exactly one L, one T, and one W are:

LTW, LWT, TLW, TWL, WLT, WTL

There are 6 favorable outcomes.

Thus, the probability is: $\text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} = \frac{6}{64} = \frac{3}{32}$

Part D: Probability that Erin drinks water two days and lemonade one day

We need to count how many outcomes have exactly two W's and one L:

The combinations that include exactly two W's and one L are:

WWL, WLW, LWW

There are 3 favorable outcomes.

Thus, the probability is: $\text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} = \frac{3}{64}$

Here are 5 questions you might ask next:

1. Can you explain how to determine the total number of possible outcomes in more detail?
2. How can we systematically count the favorable outcomes for such problems?
3. Can you show how to compute probabilities for other similar scenarios?

Tip: When dealing with probability problems, always clearly define the sample space and carefully count the favorable outcomes.
