20%
Explanation:
Total customers that ordered cold drinks = 8 + 12 + 5
Total customers that ordered cold drinks = 25
Number of customers that ordered large cold drink = 5
the probability that a customer ordered a cold drink given that he or she ordered a large = Number of customers that ordered large cold drink/ Total customers that ordered cold drinks
= 5/25 × 100
= 0.2 × 100 = 20% (nearest percent)
The probability that a customer ordered a cold drink given that he or she ordered a large = 20%
