Eric rolled a 5 on a number cube. He then rolled a 6. Are these events dependent or independent?
Thank you for helping and can you please show how you figured out the problem so know how to figure out later on problems like this one?

is there a possibility that rolling a 5 somehow affects rolling a 6? or vice versa?
OpenStudy (anonymous):
It doesn't say in the problem, but I think I found the answer. Thanks though soooo much for your help!
jimthompson5910 (jim_thompson5910):
what did you get for the answer
OpenStudy (anonymous):

OpenStudy (anonymous):
i meant dependent.
OpenStudy (anonymous):
it is?
jimthompson5910 (jim_thompson5910):
rolling a 5 does NOT affect how you roll a 6

both events have the same chance of occurring (1/6) and rolling one value does NOT change the odds of rolling the other
OpenStudy (anonymous):
yes, so wouldn't that make it dependent? Wait......
jimthompson5910 (jim_thompson5910):
no, it would make it independent
jimthompson5910 (jim_thompson5910):
each event is on its own
jimthompson5910 (jim_thompson5910):
neither event is dependent on the other
