Ответ:
a) 0.405
b) 0.269
Step-by-step explanation:
a) Let's first find the percentage chance of a voter being a republican AND a man:
0.4 * 0.6 = 0.24
Similarly for democrats that are men: 0.45 * 0.3 = 0.135
And lastly for independent voters that are men: 0.15 * 0.2 = 0.03
To solve this part, we just need to add the percentages we found above. This comes out to be: 0.24 + 0.135 + 0.03 = 0.405
b) To find the probability the person is an independent provided that she is a woman can be found by the following method.
First write down the probability the voter is a republican AND a woman. This is : 0.4 * 0.4 = 0.16
Similarly for democrats that are women: 0.45 * 0.7 = 0.315
And lastly for independent voters that are women: 0.15 * 0.8 = 0.12
To find the probability a voter is independent provided that she is a woman is: 0.16 / (0.16 + 0.315 + 0.12) = 0.269
