Question 1108402: In a town of 900 people, 400 are employed of which 300 are men,and 100 are women, if there are 600 men in d town,wat is d probability of pikin a person being a woman or unemployed Answer by ikleyn(52867) (Show Source):
1. The set {woman OR unemployed} is equal to the set {women + unemployed man}.
The last set is the union of two disjoint sets, which is easier to analyse.
2. From the condition, there are 300 = 900 - 600 women in the town.
The number of unemployed man is 600 - 300 = 300.
3. So, the set {women + unemployed man} consists of 300 + 300 = 600 persons.
Now the probability under the question = (women + unemploeyed man)/(total population) = = .
