In a test of a gender-selection technique, results consisted of

228228

baby girls and

245245

baby boys. Based on this result, what is the probability of a girl born to a couple using this technique? Does it appear that the technique is effective in increasing the likelihood that a baby will be a girl?

Solution

P(girl) = n(girls) / N = 228228 / (228228 + 245245)

= 0.482029598 [ANSWER]
