The probability of picking red button is 
<u>Solution:</u>
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:
Thus the probability that it is red is
Equilateral: all sides are the same length
isosceles: two sides are the same length
obtuse: there is 1 obtuse angle
Answer:
(9,9)
Step-by-step explanation:
Add all of the numbers 50+30+100=180 and you have to find 180s multiples which are <span>1,2,3,4,5,6,9,10,12,15,18,20,30,36,45,60,90,180. So you can do and of those numbers and just divide them by 180 to find the number of items that would be inside the box. For example, 180 divided by 3 boxes would be 60 items in each box.</span>
