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:
B. 138.7
Step-by-step explanation:
Put the given number where the variable is and do the arithmetic.
h(x) = 5.7 -19x
h(-7) = 5.7 -19(-7) = 5.7 +133 = 138.7
Answer:
x= negitive 6/8
Step-by-step explanation:
Ok think about it 1/4 plus 1/2 is 3/4
so how do i go to negitives?
you double the amount of it and then minus it
because 3/4- 3/4 would be zero
so you have to double it to get that answer
have a wonderful day filled with only joy!
