Not certain of the finalanswer?
Pr(pass)=.51
Pr(fail)=1-pr(pass)=1-.51
Use your calculator, if you need, to solve that.
Ok. I pretty much have this one solved but the final answer has me stumped. The probability that Luis will pass his statistics test is 0.51. Find the probability that he will fail his statistics test. This is what I have so far. P(fail)=.51; =1-.51. But I am not sure of the final answer. Thank you so much!

yes, but .49 does not seem realistic. I may be doing something wrong. Thanks
0.51 is about half. If he has slightly better than a 50-50 chance of passing the test, doesn't it make sense that he has a slightly less than 50-50 chance of failing it?
Oh wow, yes. you are right. That does make perfect sense! Sometimes I read to much into a problem. Thank you for simplifying for me Mrs. Sue. :)
You're very welcome, Annie.
