Explanation / Answer

solution:-
(a)Frequently = 426
Occasionally = 889
Frequently or Occasionally = 426 + 889 = 1315
Probability = Frequently or Occasionally / Total
Probability = 1315 / 2852
probability = 0.461

b)
Female total = 1375
Males not involved = 796
Female or not involved = 1375 + 796 = 2171
Probability = 2171/2852
probability = 0.761

c)
Male = 1477
Frequently involved females = 204
Total males or frequently involved = 1477 + 204 = 1681
Probability = 1681 / 2852
probability = 0.589

d)
Female 1375
Not frequently involved men = 459+796 = 1255
Female or not frequently involved = 1375 + 1255 = 2630
Probability = 2630/ 2852
probability = 0.922
