A study found that 45% of the embryo transfers performed in assisted reproductive technology (ART) procedures resulted in pregnancies. Twenty-four percent of the ART pregnancies resulted in multiple births.
(a) Find the probability that a randomly selected embryo transfer resulted in a pregnancy and produced a multiple birth.
(b) Find the probability that a randomly selected embryo transfer that resulted in a pregnancy did not produce a multiple birth.
(c) Would it be unusual for a randomly selected embryo transfer to result in a pregnancy and produce a multiple birth? Explain.
