Question

The wall is family had 100 relatives at their big Thanksgiving dinner of all the guest 90 had French heritage 80 had English heritage and 75 head Native American heritage at least how many had heritage from all three cultures?

Answer 1

The Thanksgiving tradition started between the British colonies and the Native Americans. Hence, we base only on those two nationalities. Then,

English: 100 - 80 = 20
Native Americans: 100 - 75 = 25

The total would be 20 + 25 = 45. There are a t least 45 people from all three heritages.
