Q:
# A jar contains 30 red, 30 blue, and 60white buttons. You pick one buttonat random, find the probability that itis red.

Accepted Solution

A:

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]
