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 
Answer:
3 miles = 5280 yds
5280 yds > 5,000 yds
in this case 3 miles is greater than 5,000 yards
Ratio for this mean for every 10 cats sold there was one dog
60/10 = ?
6 dogs
ratio = 60:6
3562 is greater than 979, 3562>979 Because 3562 is bigger than 979. (Did this help?)
You have to use the equation which has just slipped my mind. It say x1-y1 over x2-y2. Then you will find x. I am so sorry this equation name slipped my mind. If I remember I will let you know.
