This week we will continue to discuss probability. These problems can be very tricky for students, so you'll want to spend some time practicing outside of class. Be sure to ask lots of questions during class!
For this week's blog, in addition to the fill in the blanks, you should read the article linked below and give a brief (2-3 sentence) response to it.
Take a Statistics Class
Challenge Problem: According to the U.S. Census Bureau, the
probability that a randomly selected worker primarily drives a
car to work is 0.867. The probability that a randomly selected
worker primarily takes public transportation to work is 0.048.
(a) What is the probability that a randomly selected worker primarily
drives a car or takes public transportation to work?
(b) What is the probability that a randomly selected worker
neither drives a car nor takes public transportation to
work?
(c) What is the probability that a randomly selected worker does
not drive a car to work?
(d) Can the probability that a randomly selected worker walks to
work equal 0.15? Why or why not?
