Give three examples of Bernoulli rv's (other than those in the text). (Select all that apply.) Ox = 1 if a randomly selected shopper purchases a food item at a department store and X = 0 otherwise. Ox = the number of lightbulbs that needs to be replaced in a randomly selected building and x = 0 if there are none. Ox = 1 if a randomly selected lightbulb needs to be replaced and X = 0 otherwise. Ox = the number of food items purchased by a randomly selected shopper at a department store and X = 0 if there are none. Ox = 1 if a randomly selected day has a high temperature of over 100 degrees and X = 0 otherwise. Ox = the number of days in a year where the high temperature exceeds 100 degrees and X = 0 if there are none.
