4. Simulation A student wants to simulate three births, so she writes “male” on one index card and “female” on another. She shuffles the cards, then selects one and records the gender. She shuffles the cards a second time, selects one and records the gender.

She shuffles the cards a third time, selects one and records the gender. Is this process okay for simulating three births?

In Exercises 5–8, describe the simulation procedure. (For example, to simulate 10 births, use a random number generator to generate 10 integers between 0 and 1 inclusive, and consider 0 to be a male and 1 to be a female.)
