Possible answer: The two-way tables from exercise 7 was:

LeftRightTotalFemale11104115Male2492116Total35196231

Two events could then be male (A) and right handed (B). From the table, P(A)=11631 and P(B)=196231 since there are 116 males and 196 right handed people. Since there are 92 right handed males and 116 males, then P(BA)=92116 From the table, there are 196 right handed people and 92 of them are male so P(AB)=92196=2349. Using Bayes’ Theorem, P(BA)=P(BA)P(A)P(B)=92116116231196231 which is equal to the previous answer you found.
