Answer:
<em>The probability that the button is not white is </em><em>0.583</em>
Step-by-step explanation:
The jar contains 30 red, 40 blue, and 50 white buttons.
In total there are 120 buttons in the jar. So,
Let us assume that, A be the event of picking white buttons, so
So the probability of picking white button is,
Then the event 
will be not picking up white buttons, so the probability of not picking up white buttons is,
Answer:
Advantages of representing a function as an equation instead of graph :
- No chance of misinterpretation of the data as making graph involves more data as compared to data needed to represent function as an equation.
- Drawing graphs may be inconvenient in case you need to plot fraction and decimal functions.
Disadvantages of representing a function as an equation instead of graph :
- Visualization is easy in case of graph. Many factors such as maximum, minimum can be easily seen with the help of graph as compared to that of equation of the function.
- With the help of curve of the graph, we can identify the nature of the function much easily than by the equation of the function.
