YSORT Gender Selection MicroSort's YSORT genderselection technique is designed to increase the likelihood that a baby will be a boy. In updated results (as of this writing) from a test of MicroSort's YSORT gender-selection technique, 291 births consisted of 239 baby boys and 52 baby girls (based on data from the Genetics & IVF Institute). Based on these results, what is the probability of a boy born to a couple using MicroSort's YSORT method? Does it appear that the technique is effective in increasing the likelihood that a baby will be a boy?

Answer

Step 1 of 2

Probability of a boy born to a couple is 239/291=0.821

Probability of a girl born to a couple is 52/291=0.179
