Roughly 1 in 6 students enrolled in higher education took at least one online course last fall. 
If 5 enrolled students are chosen at random, 

(a) what is the probability that all 5 took online courses? 

(b) What is the probability that at least 1 took an online course?



<pre>
(a)  P = {{{(1/6)^5}}} = {{{1/6^5}}} = {{{1/7776}}}.    <U>ANSWER</U>



(b)  P = {{{1 - (5/6)^5}}} = {{{1 - 3125/7776}}} = {{{(7776-3125)/7776}}} = {{{4651/7776}}} = 0.5981  (rounded).   <U>ANSWER</U>
