Here b = 13 and h = 4 , thus

A = \frac{1}{2} × 13 × 4 = \frac{1}{2} × 52 = 26 units² → A

find the total number of possible outcomes for four different cell phone models each of which has 3 different plans
Oksanka [162]
Hello!

I believe there are a total of 12 possible outcomes for this problem. Using simple math, you can just multiply 4 by 3 to get 12 possible outcomes but you can also get 12 outcomes by looking at the fact that since there are 3 plans in each of the 4 models, there are 12 ways that this could play out.

I hope this helps!
