What is the probability of getting pregnant if sperm come out?
Depends on how far along the woman is in her monthly cycle of menstruation and ovulation. Women are most fertile two days before through two days after they ovulate, which occurs approximately 14 days after their last menstrual cycle. However, sperm has been said to survive up to 72 hours after coitus (sex). Even if a man does not ejaculate (i.e. "pulls out"), sperm is still released during sex, in the form of pre-ejaculate (which occurs during coitus and is virtually undetectable by either partner). Therefore, you CAN get a girl pregnant even if you pull out, and there is a good week or more that she can easily get pregnant out of each month--and that week is actually harder to pin down than just counting calendars.

Since there is no absolute mid-point, we take the two middle numbers , add them and divide by '2'. Hence. ( 68+72)/2 = 70 MODE: is the term that occurs most frequently. In this case '72'. as there are two of them , but only one each of the other terms. MEAN; Add all the terms and divide by the number of terms. (46+57+68+72+72+93) / 6 = 408/6 = 68
