.
Step-by-step explanation:
It is given that the box contains 14 red balls,12 blue balls,and 9 yellow balls. The total number of balls is

The probability is defined as

Probability of getting red ball = 
Probability of getting blue ball = 
Probability of getting yellow ball = 
It is given that a ball is drawn at random and the color is noted and then put back inside the box. It means first event will not effect the probability of second event.
a.
The probability of both balls are blue is

C (i think)
Step-by-step explanation:
of course you get right to safety, choose, and to have dignity
9x + 85 = 1215
9x = 1130
x = about 125.56 minutes each time
The answer is H because since there is 4 quarts in a gallon, you can divide 24 by 4. Hope this helped!
