Hello, can you help me solve these statistics questions a-e? Thank you

OUR TEACHER PRACTIC Listed is a series of experiments and associated random variables. In each case, identify the values that the random variable can assume and state whether the random variable is discrete or continuous. (a) Take a 40-question examination. random variable x = number of questions answered correctly Identify the values that the random variable can assume. O 0, 1, 2, .. O 0, 1, 2, ..., 40 Ox>0 O OSX s 40 O none of these State whether the random variable is discrete or continuous. O continuous O discrete (b) Observe cars arriving at a tollbooth for 3 hours. random variable x = number of cars arriving at tollbooth Identify the values that the random variable can assume. O 0, 1, 2, .. O 0, 1, 2, ..., 24 O x>0 OOSX53 O none of these State whether the random variable is discrete or continuous. O continuous O discrete(e) Weigh a shipment of goods. random variable x = number of pounds Identify the values that the random variable can assume. O 0, 1, 2, ... O 0, 1, 2, ..., 16 O x > 0 Oosxs1 O none of these State whether the random variable is discrete or continuous. O continuous O discrete Need Help?

O 0, 1, 2, ..., 42 O x > 0 O OS X 5 42 O none of these State whether the random variable is discrete or continuous. O continuous O discrete (d) Observe an employee's work. random variable x = number of nonproductive hours in a seven-hour workday Identify the values that the random variable can assume. O 0, 1, 2, ... O 0, 1, 2, ..., 7 O x > 0 OOSX5 7 none of these State whether the random variable is discrete or continuous. O continuous O discrete
