Why would it be a problem if only 1 sperm made it all the way to the egg?
It would be a problem if only one sperm made it all the way to the egg because there is a layer around the females egg that is 'broken down' by the reaction of an enzyme in the head of the sperm, it's like many hundreds of sperms 'drill' a way through this layer. One single sperm wouldn't be able to get in to the egg to fertilize it.
