There is 46% probability of experiencing neither of the side effects.
<h3>What is probability ?</h3>Probability shows possibility to happen an event, it defines that an event will occur or not. The probability varies from 0 to 1.
Given that,
While taking drug, chances of experiencing nausea (n)= 24 %,
Chances of experiencing decreased sexual drive (d) = 46 %.
Also, there are 60% chances of experiencing both side effects.
Use vain diagram to solve this type of questions,
Total chances of experiencing side effects = 8 + 30 + 16 = 54
The chances of experiencing neither of the side effects = 100 - 54 = 46
So there is 46% probability of experiencing neither of the side effects.

Putting the considered items in order from most expensive to least expensive item gives the order as shown by: Option b. Blender, ink, hat, heater
<h3>What is Markup and Markdown?</h3>Markup is the amount that will be increased in the original price of the considered thing.
Markdown is the amount that will be decreased from the original price of the considered thing.
Think of "up" and "down" as increasing and decreasing prices respectively.
<h3>How to find the percentage from the total value?</h3>Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Thus, that thing in number is
For this case, the base prices and the chage in price is given as:
Item Base Price Change Direction
Blender $29.73 9% Markdown
Hat $14.16 77% Markup
Ink $20.17 27% Markup
Heater $28.46 22% Markdown
Calculating the resultant price:
- Case 1: Blender:
Resultant price = 29.73 - 9% of 29.73
- Case 2: Hat:
Resultant price = 14.16 + 77% of 14.16
- Case 3: Ink:
Resultant price = 20.17 + 27% of 20.17
- Case 4: Heater:
Resultant price = 28.46 - 22% of 28.46
Thus, putting the considered items in order from most expensive to least expensive item gives the order as shown by: Option b. Blender, ink, hat, heater
