Is it unlikely to randomly select an adult American and get someone who knows that October 18 is National Statistics Day in Japan?
Explanation / Answer
as there are 365 days, each day has equal probabilty of being his bth day.
hence probability that his or her birthday is October 18 =1/365
there are 31 days in october

it is unusually less probable event as there are only few people who are american and are involved with Japan through business, travel or work, as well specifically into statistics.
