A school canteen serves lunch for students. A set of menu consist of a nice, 1 type
of viand (chicken adobo, pork adobo and pinakbet). and 1 type of drinks (coke
sprite and orange) What is the probability that a student chose pork adobo and
sprite? Construct a tree diagram that shows the possible menu combinations
pairs of viand and drinks
chicken adobo + coke
chicken adobo + sprite
chicken adobo + orange
pork adobo + coke
pork adobo + sprite
pork adobo + orange
pinakbet + coke
pinakbet + sprite
pinakbet + orange
3 viand x 3 drink = 9 pairs
there is only one pair for chicken adobo and sprite
therefore the probability for getting this pair
= 1/9
