What is the conditional probability that Taster 2’s rating is higher than 3 when Taster 1's rating is a 3? If Taster 1’s rating for a wine is 3, what is the conditional probability that Taster 2’s rating is higher than 3? 1 2 3 4 5 1 0.03 0.02 0.01 0.00 0.00 2 0.02 0.08 0.05 0.02 0.01 3 0.01 0.05 0.25 0.05 0.01 4 0.00 0.02 0.05 0.20 0.02 5 0.00 0.01 0.01 0.02 0.06 Taster 2 is the horizontal columns and Taster 1 is the vertical columns. I know to find P(B|A) = 0.06/P(Taster 1 rating 3). I've tried P(B|A) = 0.06 / 0.01 = 6 which makes no sense I also did P(B|A) = 0.06 / 3(for rating of 3) = 0.02 I'm not sure what the probability of Taster 1 rating a 3 is...

There are $5$ things that could have happened with the given information. Taster $1$ gives a $3$, then taster $2$ gives a $1$, etc.

Then find the probability that taster $2$ rates a $4$ or $5$, $.06$, then divide by $.01+.05+.25+.05+.01=.37$ to get $.06/.37=\dots$
