Step-by-step explanation:
First, We do the multiplication law. which states that if
R can occur multiple ways, n, then the total numbers of ways is just
In this case, we have 3 things to consider so we just do
number of sandwiches which is 3: Number of sides to choose from which is 2: And number of drinks: 2 so we do
So there is 12 possible combinations. Now let see which ones contine chips and juice.
We can make a tree diagram, and see that we can do
Chicken,Chips, and Juice
Turkey, Chicken,Juice
Or Veggie,Chicken, and Juice so there is 3 combinations that includes that.
So out of 12 combinations, there is 3 that favor our scenario so we say
Probability is 3/12=1/4=25%
