Here's the question:
In rolling a fair die, Find the probability of rolling a 1 before an even number? All I'm given as a hint is to consider
P(1|1 or even)
I know it's conditional probability, I just don't know if i need to use Bayes' theorem or something different, i know the answer is 1/4 but for some reason I keep coming up with 1/2, which cannot be right at all. I feel like I'm making a really dumb mistake and have been working on this one for hours.
