#2) A new cell phone is available in five colors: white (W), black (B), gold (G), silver (S), and red (R), and three sizes: 32GB, 128GB and 256GB. A probability experiment consists of randomly selecting a color and a size.
A) Draw a tree diagram to show the possible outcomes of the experiment. B) List the sample space for this experiment AND state the total number of outcomes in the sample space. C) Explain how the fundamental counting principle can also be used to find the total number of outcomes in the sample space. D) Show your work to find the probability of selecting a silver, 32GB phone using the formula for classical probability, then state whether this is considered unusual.
