90 of 100: The Safer Sheep

Probability Level 1

Each sheep has two fences (represented by matchsticks) protecting it from the wolf. If two matchsticks are removed at random from each sheep's fencing, which sheep is more likely to survive?

A sheep survives if one of its two fences is intact after the matchsticks are removed.
