It is reported that 20% of the Republicans, 51% of the Democrats and 29% of Independents favor some type of corporate tax reform. Suppose a member of Congress is randomly selected and he/she is found to favor some type of corporate tax reform. What is the probability that this person is a Democrat

Answer 1

Check the explanation.

Explanation:

Let, the total population is 1000.

The number of republicans are 26% that is 260, Democrats are 63% that is 630 and Independents are 11% of 1000, that is 110.

20% of 260 =
`(20*260)/(100) = 52` Republicans favor some type of corporate tax reform.

51% of 630 =
`(51*630)/(100) = 321.3` .

29% of 110 =
`(29*110)/(100) = 31.9`.

Total number of people, who favor some type of corporate tax is (52 + 321.3 + 31.9) = 404.2 ≅404.

The required probability is
`(321)/(404)`.
