Determine whether the random variable is discrete or continuous. In each case, state the possible values of the random variable. (a) The number of light bulbs that burn out in the next week in a room with 19 bulbs. (b) The amount of rain in City B during April. (a) Is the number of light bulbs that burn out in the next week in a room with 19 bulbs discrete or continuous? O A. The random variable is discrete. The possible values are 0≤x≤ 19. O B. The random variable is continuous. The possible values are 0≤x≤ 19. O C. The random variable is continuous. The possible values are x = 0, 1, 2,..., 19. O D. The random variable is discrete. The possible values are x = 0, 1, 2,..., 19. (b) Is the amount of rain in City B during April discrete or continuous? O A. The random variable is discrete. The possible values are r20. O B. The random variable is continuous. The possible values are r20. O C. The random variable is discrete. The possible values are r= 1, 2, 3, .... O D. The random variable is continuous. The possible values are r= 1, 2, 3, ....
