You never have an around 100% chance. You always have less. The chance of at least one out of ten making it if they have 10% chance each is: 1-0.9^10, that's two thirds.
In other words: In a society where 90% of children die and women have 10 births, one third of the mothers will lose all. All assuming the deaths are independent of course.
It's a natural response to the hardship. If the chance that the kid make it is 10%, then make 10 times more kids. That way you have around 100% chance that your lineage makes it through life.
