Answer:
5/12
Step-by-step explanation:
So probability is favorable outcome/total number of outcomes
So first we need to find how many pople there are in total.16+20+7+5=48
Now there are 20 people who like both cream and sugar.
So our fraction would be 20/48
We can divide both the numerator and denominator by 4 to simplify the fraction.
5/12
Or as a percentage it would be 41.67%
