those were the instructions and stuff

Answer 12

you didn't put the data in a table that captures what you want to find. it should be something like this...

in box A should be the number of respondent that answered both questions "Yes"
in box B should be the number of respondent that answered NSA "Yes" and Snowden "NO"
in box C should be the number of respondent that answered NSA "No" and Snowden "Yes"
in box D should be the number of respondent that answered both questions "No"

Answer 13

A+B+C+D = 50 (total number of respondents)

Answer 14

or A+B+C+D = total number of respondents that answered both questions

Answer 15

okay that kinda makes sense, i'll tag you again if i need help. thanks! @pgpilot326

Answer 16

you're welcome

Answer 17

if you do like that then you can say A is the event that they answered Snowden "Yes" and B is the event that they answered NSA "Yes" or something along those lines. Then you can compare P(A|B) to P(B|A)
