The odds of having only girls can be calculated for each individual pregnancy. The probability of having a girl is roughly 50% for each child. Therefore, the chance of having multiple girls in a row is the product of 0.5 for each child. For example, having three girls in a row is 0.5 0.5 0.5, which equals 12.5%.
