Suppose that 40% of all families in your city have a dog, and you want to create a simulation to predict the probability that it will take at least 4 random picks from the population to find one family with a dog.

Choose all that correctly describe the use of random digits as a simulation to predict the probability.

Use ten digits ( 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9 ), and let 40% of the them represent families with dogs.

Let the digits 0, 1, 2, 3 represent families with dogs, and (4, 5, 6, 7, 8, 9) represent families without dogs.

Find the probability that a 0, 1, 2, or 3 is not generated within the first four random picks.
