Question: Given a cryptographic hash function h that outputs a 4 - bit hash value, a brute - force attack to find a second preimage needs

Given a cryptographic hash function h that outputs a 4-bit hash value, a brute-force attack to find a second preimage needs to evaluate the hash function on average about X times. And a brute-force attack to find a collision needs to evaluate the hash function on average about Y times. What are X and Y?
