Find the total number of possible outcomes for 4 different cell phone models, each of which has 3 different plans.

A. 7
B. 12
C. 16
D. 24

The total number of possible outcomes is found by multiplying the number of options for each decision. In this case, there are 4 different models and 3 different plans for each model, so we can use multiplication to find the total number of outcomes:

4 models × 3 plans per model = 12 total outcomes

Therefore, the answer is B. 12.

To find the total number of possible outcomes for 4 different cell phone models, each of which has 3 different plans, we multiply the number of options for each model.

Since we have 4 different cell phone models and each model has 3 different plans, we can multiply as follows:

4 models × 3 plans = 12 possible outcomes.

Therefore, the correct answer is B. 12.
