The male to female human sex ratio varies, due to Demographics, environment, sex deterministic abortion, and imbalance in the male/female sperm viability ratio. The secondary ratio of boys to girls is about 105 to 100, or about 0.525 male. Estimates of the current birth sex ratio is about 0.535 male. The current global sex ratio (population) is about 0.507 male (2010) to 0.508 male (projected 2011).

What is the probability the human offspring will be female?

51%..


What is approximate probability that a human offspring will be female?

50%, or half. Therefore, there is an equal chance that the offspring will be female.


What is the probability of a human offspring being female?

50% because the male and female would both have the chance


What is the approximate probability that a human offspring will be female?

P(female offspring) = 0.5 = 1/2 Reason, In the human genetic system, a male has 'XY' chromosomes A female has 'XX' chromsomes. I will designate the femle chromosomes as X' & X" to distinguish . Hence Male is XY Female is X'X" They can match in the following manner. XX' = female XX" = female YX' = male YX" male. So you can see that there are two female outcomes and two male outcomes, out of a total of four(4) possible outcomes. So 2/4 = 1/2 = 0.5 in both cases. Hence P( female outcome) = 0.5 NB In reality, with a deeper understaning of statisitical and genetic analysis, slightly more females are born that males. Also males are slightly weaker at birth, there by making males less likely to survive at birth. This difference is only about M:F :: 49% : 51% , so equality of numbers remains roughly equal.


What is the probability of a girl getting pregnant if hymen is not broken and guy doesn't release sperm?

The probability is quite low, BUT it isn't zero, and this is a very risky practice. Human nature being what it is, the intention not to break the hymen and not to release sperm is one of those intentions that lead to Hell (so to speak). Beyond that, there is the risk of various diseases that is not in the least diminished.
