A spinner is divided into 8 congruent sections numbered 1-8. The spinner is spun once. Find the probability:
30) P(6 | even)
32) P(odd # and 5)
38) P(# greater than 8)
 
Why would you name a post "easy" and then show none of the "easy" work? It makes no sense.

You should know this: \(\displaystyle p(A|B) = \dfrac{p(A \cap B)}{p(B)}\)

\(\displaystyle p(6|Even) = \dfrac{p(6 \cap Even)}{p(Even)} = \dfrac{p(6)}{p(2, 4, or\;6)} = \dfrac{1/3}{3/6}\)

Can you do the other easy ones, now? Show us what you get.

I mean it's easy for whoever could answer the questions. Obviously, not easy to me, that's why I'm asking the question. "Easy" so it attracts the attention of math-whiz's.

Edit: [tkhunny] Remove profanity

So, you're saying that you're NOT going to try one on your own?
