Random Variables

A random variable Z is a real valued function of the type Z: S → R on a sample space S. That means the function assigns a real number to every primitive event in the sample space. In other words, a random variable is a function mapping a sample space S to a set of real numbers R.

The Frequentist approach says that given 10 coin flips you should get exactly 5 heads and 5 tails. Question 15 options: True False The Frequentist approach says that, in the long run, if we flip a coin a large number of times, we would expect an approximate 50-50 split of heads and tails. Question 16 options: True False Consider multiple trials of flipping a fair coin. As the number of trials decreases, the closer we get to an equal split of heads and tails. Question 17 options: True False The following would represent probability from the Frequentist approach: After rolling a six-sided die 300 times, we would expect to roll a 2 or a 3 about 33% of the time.
