The probability of picking red button is [tex]\frac{1}{4}[/tex]
Solution:
Given, A jar contains 30 red, 30 blue, and 60 white buttons.
You pick one button at a random choice,
We have to find the probability that it is red button.
Now, total number of buttons = 30 + 30 + 60 = 120 buttons.
Number of favourable cases for red button = 30 red buttons.
The probability of an event is given as:
[tex]\text { probability of a event }=\frac{\text { favourable ways to pick red }}{\text { total possiblities }}[/tex]
[tex]=\frac{30}{120}=\frac{1}{4}[/tex]
Thus the probability that it is red is [tex]\frac{1}{4}[/tex]
