Because frogs have a high mortality rate, meaning that a high percentage of the eggs will never make it to adulthood. They lay a lot of eggs because even if 1% of the eggs make it to adulthood, if you lay 5,000 eggs you still get 50 that make it to adulthood.
Because they don't look after the eggs they don't have much chance of surviving, so if they lay hundreds at least 3 or 4 will survive allowing the species to continue.
