In a recent year, about 36% of all infants born in a country were conceived through in-vitro fertilization (IVF). Of the IVF deliveries, about twenty-six percent resulted in multiple births. (a) Find the probability that a randomly selected infant was conceived through IVF and was part of a multiple birth. (b) Find the probability that a randomly selected infant conceived through IVF was not part of a multiple birth. (c) Would it be unusual for a randomly selected infant to have been conceived through IVF and to have been part of a multiple birth? Explain. (a) The probability that a randomly selected infant was conceived through IVF and was part of a multiple birth is 0.094. (Round to the nearest thousandth as needed.) (b) The probability that a randomly selected infant conceived through IVF was not part of a multiple birth is. (Round to the nearest thousandth as needed.)
