ok, any more information given?

perl · Answer

if we assume that you can't surf the internet and read a book at the same time, you can add those percentages to get the probability of surfing the internet or reading a book

So 31%  or 31/100 in fraction form would be the answer? Each question that is asking the probability of this OR that....I just add the 2?

perl · Answer

yes you can add them

perl · Answer

but you need to assume you can't do both at the same time

perl · Answer

also sometimes probability is given as a decimal, not a percentage
