Answer:
1/5 or 20%
Step-by-step explanation:
Since the customer ordered a cold drink, that reduces our sampling population to 25 (8 + 12 = 5).
Out of those 25 people, 5 ordered a large size.
So, the probability that someone who has ordered a cold drink ordered a large one is 5 out of 25...
P = 5 / 25 = 1/5 or 20%
