Question

Quizplus · Accepted Answer

The probability of all boys or all girls in a group of four siblings, given equal birth probabilities, is calculated as follows: For all boys, it's (1/2)^4 = 1/16, and the same for all girls, making it 1/16 for each scenario. To find the probability of either all boys or all girls, we add these probabilities together: 1/16 + 1/16 = 1/8.
