about 1/300, but it also depends on age and family history
Our doctor told us the probability was 4%.
Ans : Probability that there will be at least one case of twins = 1-(79/80)^20
Women who are themselves fraternal twins have a 10% chance of producing twins, identical twin women have only a 0.6% probability of having a twin birth.
Probability of girl, assumed to be 0.5. Therefore, probability of 5 girls is 0.5^5 or 0.03125.
It is possible to have multiple sets of multiples, and giving birth to multiples can also skip a generation. Hyper ovulation (the tendency to release multiple eggs during ovulation, increasing the chances of conceiving fraternal twins) is a factor in giving birth to twins.
Depends like adopt or giving Birth if adopt how many you want but giving Birth maybe 1 or like twins 2
definitely. It usually skips a generation or more but if someone is a twin, they have a larger chance of giving birth to twins than someone who isn't a twin or comes from a bloodline of twins.

Having twins is based on probability. There is not a 100% chance you will have twins.
Identical twins happen by chance only; 4 per 1000 births or 0.004 probability. Fraternal twin probability is increased only if it is on the mother's side; so this does you affect your circumstance (from what you have stated). The chance of fraternal twins is 1 in 60 or 0.017. So, your probability of identical twins is 0.004 and fraternal twins is 0.017 (BTW, I have triplets).
Whether the dam was a twin herself may have a little influence on her odds of giving birth to twins. Normally twins occur in one out of 1000 births.
