A survey found that 50% of teenagers prefer to watch a movie at a theater over other viewing options. You want to know the estimated probability that three out of four randomly chosen teenagers do not prefer watching a movie at a theater. How could you design a simulation for this situation?
Flip a fair coin four times, with heads representing teenagers who prefer watching a movie at a theater and tails representing those who do not.
Pick a card from a deck of standard playing cards four times, with red suits representing those who prefer watching a movie at a theater and black suits representing those who do not.
Spin a spinner with four equal sections three times, with one section representing each person.
Roll a six-sided die four times, with even numbers representing those who prefer watching a movie at a theater and odd numbers representing those who do not.
Generate a set of four numbers using a number generator, with numbers 0 to 5 representing those who prefer watching a movie at a theater and 6 to 9 representing those who do not.

Answer 1

An equivalent situation, in which the binomial distribution could be used, is given by:

Flip a fair coin four times, with heads representing teenagers who prefer watching a movie at a theater and tails representing those who do not.

What is the binomial distribution formula?

The formula is:

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$C_{n,x} = \frac{n!}{x!(n-x)!}$

The parameters are:

• x is the number of successes.

• n is the number of trials.

• p is the probability of a success on a single trial.

For this problem, the parameters are:

p = 0.5, n = 4;

The other situation that would represent a binomial distribution with the same parameters is given by:

Flip a fair coin four times, with heads representing teenagers who prefer watching a movie at a theater and tails representing those who do not.

The other situations have different values of p, hence they are not equivalent.
