When a woman is injected with an egg fertilized in vitro, the probability of its implanting successfully is 20 percent. If a woman is injected with five eggs simultaneously, what is the probability that she will become pregnant? (Part c is from Margaret Holm.)

In a recent year, about 37% 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 (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.) (c) Would it be unusual for a randomly selected IVF cycle to result in a pregnancy and produce a multiple birth? Explain. Choose the correct answer below. A. Yes, this is unusual because the probability is less than or equal to 0.05. B. No, this is not unusual because the probability is not less than or equal to 0.05. C. No, this is not unusual because the probability is less than or equal to 0.05. D. Yes, this is unusual because the probability is not less than or equal to 0.05.

4. 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-five 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 ___ (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.) (c) Would it be unusual for a randomly selected IVF cycle to result in a pregnancy and produce a multiple birth? Explain. Choose the correct answer below. A. No, this is not unusual because the probability is not less than or equal to 0.05. B. Yes, this is unusual because the probability is less than or equal to 0.05. C. Yes, this is unusual because the probability is not less than or equal to 0.05. D. No, this is not unusual because the probability is less than or equal to 0.05 5. A doctor gives a patient a 90% chance of surviving bypass surgery after a heart attack. If the patient survives the surgery, then the patient has a 50% chance that the heart damage will heal. Find the probability that the patient survives the surgery, and the heart damage heals. The probability is ___
