17. 17. Week 4 Lab Lecture<br />For the first one, x ≥ 1, you would add all of the probabilities from 1 through 10 for 2/5 or calculate 1 – P(0)<br />
18. 18. Week 4 Lab Lecture<br />For the second one, x > 1, you would add all of the probabilities from 2 through 10 for 2/5 or calculate 1 – (P(0)+P(1))<br />
