In a test of a​ gender-selection technique, results consisted of 221 baby girls and 224 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?       The probability that a girl will be born using this technique is approximately enter your response here. ​(Type an integer or decimal rounded to three decimal places as​ needed.) Does the technique appear effective in improving the likelihood of having a girl​ baby?
