Give three examples of Bernoulli rv's (other than those in the text). (Select all that apply.) X = the number of fiction books owned by a randomly selected student and X 0 if there are none xthe number of lightbulbs that needs to be replaced in a randomly selected building and X-O if there are none. X = 1 if a randomly selected book is fiction and X = 0 otherwise 0 x = 1 if a randomly selected driver has automoble insurance and X = 0 otherwise. 0 X = 1 if a randomly selected lightbulb needs to be replaced and X-0 otherwise. = the number of accidents caused by a randomly selected driver and X = 0 if there are none.

Explanation / Answer

A Bernoulli random variable can take two values: X = 1 and X = 0, and it's value is random. These are the 3 examples which are Bernoulli random variables:

- X = 1 if a randomly selected book is fiction and X = 0 otherwise

- X = 1 if a randomly selected driver has automobile insurance and X = 0 otherwise

- X = 1 if a randomly selected lightbulb needs to be replaced and X = 0 otherwise
