A​ gender-selection technique is designed to increase thelikelihood that a baby will be a girl. In the results of the​gender-selection technique, 873 births consisted of 452 baby girlsand 421 baby boys. In analyzing these​ results, assume that boysand girls are equally likely. (Round 4 demicals if needed)
a. Find the probability of getting exactly 452 girls in 873births.
b. Find the probability of getting 452 or more girls in 873births. If boys and girls are equally​ likely, is 452 girls in 873births unusually​ high?
c. Which probability is relevant for trying to determine whetherthe technique is​ effective: the result from part​ (a) or theresult from part​ (b)?
d. Based on the​ results, does it appear that the​gender-selection technique is​ effective?
