If one student is chosen at random, find the probability that the student was male GIVEN they got a 'C':
Expert Solution
Step 1
Given that : 3×3 contingency table
Here we use empirical probability
P(a) = n(a) / n(s)
And conditions probability
P{A/B} = P{ A and B }/ P(B)
Additional rule of probability.
