Basic Principles of Probability. Definitions. Probability is a measure of how likely it is (or how probable it is) that a given event will occur. The more likely an event is, the higher its probability. The sample space is the set of possible outcomes within a given context. The sample space is equivalent to the universal set.
But after your water breaks, you must not get an internal/vaginal exam. You have a health problem that puts you or your baby at risk. If you have conditions like diabetes, high blood pressure, preeclampsia, or eclampsia, your doctor or midwife might want to induce labor.
When my water broke at 37 weeks I thought it was sweat. My husband finally convinced me to go to the hospital (we had been there 3 times with false alarms) and the baby had almost no amniotic fluid left. This resulted in a fever and eventually in complications with hemorraging from prolonged labor and infection.
