a) Find the probability that a random selected ART cycle resulted in a pregnancy and produced a multiple birth.

b) Find the probability that a random selected ART cycle that resulted in a pregnancy did not produce a multiple birth.

c) Would it be unusual for a randomly selected ART cycle to result in a pregnancy and produce a multiple birth?

2. The amounts a soft drink machine is designed to disperse for each drink are normally distributed, with a mean of 11.7 fluid ounces and a standard 0f 0.3 fluid ounce. A drink is randomly selected.

a) Find the probability that the drink is less than 11.6 fluid ounces.

b) Find the probability that the drink is between 11.3 and 11.6 fluid ounces.

c) Find the probability that the drink is more than 12.2 fluid ounces.
