Splet21. sep. 2024 · I think I would do (4/7) * (3/6). P(A and B) is found by multiplying the two. The key thing here is that you are getting the probability $\frac36$ by assuming there are only $6$ marbles remaining and $3$ of them are yellow. That is, you have found a probability of drawing a yellow marble on the second draw that is correct only if the first … Splet当p(a)和p(b)不相关时，p(ab)=p(a)*p(b)；当p(a)和p(b)相关时，p(ab)=p(a b)*p(b)或者p(ab)=p(b a)*p(a)。 changes in 2021 tax filing https://druidamusic.com
