Answer:
0.31
Step-by-step explanation:
% conservatives = 30 ; voted = 65%
% Liberals = 50 ; voted = 82%
% Independents = 20 ; voted = 50%
If a person in the city is selected at random and it is learned that she did not vote in the last election, what is the probability that she is a liberal
Number that did not vote :
% conservative × (1 - voted) + % Liberals × (1 - voted) + % conservatives × ( 1- voted)
(30% × 0.35) + (50% × 0.18) + (20% × 0.5)
(0.3 × 0.35) + (0.5 × 0.18) + (0.2 × 0.5)
= 0.105 + 0.09 + 0.1 = 0.295
Hence, probability that a person chosen at random did not vote and she's a liberal :
P = liberal who did not vote / total who did not vote
P = (0.5 × 0.18) / 0.295
P = 0.09 / 0.295
= 0.30508
= 0.31
