If 45% of people chose coffee and 25% of people chose juice, but 15% of people chose both, then we’d have to subtract 15% from both amounts to find the percentage of people who chose that specific drink.
45-15=30% 25-15=10%
Now add those two together to get how many people prefer coffee or juice. 30+10=40%. If 40% out of 100% of people prefer coffee or orange juice, then the remaining percent of people must not prefer either of them.
100-40=60%.
Therefore, 60% of people prefer neither coffee nor juice.
