Question 890976
To do this mathematically, more information is needed.
However, I looked up some information for you.  The <a href=http://duckduckgo.com>search engine</a> is your friend, assuming you are allowed to use it.
Normal hemoglobin for an adult male is 14 to 18 (*information is not from a medical professional)
A hemoglobin of 8.9 is considered anemic.
The probability of an adult male having a hemoglobin of 9.0 or above would mean that he is non-anemic.
Unless that adult is vegetarian, his likelihood of being lower than 9.0 is less than 1% in the US (up to 13% for vegetarians, 9-16% for women of childbearing age).
