Answer 1

The​ odds, in the most simplified​ form, are 7 to 3 against a randomly selected​ 18- to​ 34-year-old having cursed at his or her computer.

Explanation:

Given

`p = 30\%` ---- proportion that cursed their computer

Required

Odds against the selected

Using the complement formula, the proportion that the selected has not cursed at their computer is:

`p' = 1 - p`

`p' = 1 - 30\%`

`p' = 70\%`

So, the odds against the selected is:

`Odds = p' : p`

`Odds = 70\% : 30\%`

Divide by 10%

`Odds = 7: 3`
