Explanation / Answer

(a)Here,

Pr(Frequently involved or occassinally involved) = (431 + 882)/2854 = 0.460

(b) Pr(Being female or not being involved) = Pr(Female) + Pr(Not being involved) + Pr(Female and not being involved) = (1387 + 1541 - 748)/2854 = 0.764

(c) Pr(Male or Frequently involved in charity work) = Pr(Male) + Pr(Frequently involved) + Pr(Male and Frequently involved) = (1467 + 431 - 222)/2854 = 0.587
