A) 0
B) 1
C) 2
D) 3
E) 4
Let's start filling in each region, starting with a
a) 3 works here, since it's a prime number, but it's neither even nor divisible by 5
b) 5 works here (it's prime AND it's divisible by 5)
c) 15 (divisible by 5, but neither even nor prime)
d) EMPTY. In order for a number to be in this region, it must be prime AND divisible by both 2 and 5. There is no such number.
e) 2 is is both prime and even
f) 10 is even and divisible by 5 (but not prime)
g) 4 is even, but neither prime nor divisible by 5
h) 9 works here
So, only one region is left empty
Answer: B
Cheers,
Brent
