Answer:

33.33%

Step-by-step explanation:

Probability is a percentage.  To determine probability you would add all of the buttons together to equal 120 buttons.  Then you would divide the number of blue buttons by that total or 40/120 which equals 0.333333; this number in a percentage is 33.3333% (or roughly 1/3).  

Answer:

  • 33.33%

Step-by-step explanation:

To find the probability of blue buttons, divide the amount of blue buttons with the total buttons.

  • Blue Buttons/Total Buttons
  • => 40/30 + 40 + 50
  • => 40/120
  • => 1/3 = 33.33%

Hence, the probability of the button chosen is blue is 33.33%.
