A) 2 B) 4 C) 8 D) 29 E) 32
lets assign variables to all the areas in Venn Diagram of Three.   three different Units are 29OG, Cat, Snake= Total = 59   Only 29og= d=15   Only Cat = c=10   Only Snake = s   Exactly 29og and Cat= 5   Exactly 29og and Snake = x   Exactly Cat and Snake = y   all three= 3   so 59=15+10+5+3+x+y+s   we need to know total snakes= x+y+s+3 = 29   answer:29
<result>D</result>
