A gender-selection technique is designed to increase the likelihood that a baby will be a girl. In the results of the gender-selection technique, 969 births consisted of 494 baby girls and 475 baby boys. In analyzing these results, assume that boys and girls are equally likely. a. Find the probability of getting exactly 494 girls in 969 births. b. Find the probability of getting 494 or more girls in 969 births. If boys and girls are equally likely, is 494...
