CHAPTER 1,2/CLO 1,2
9. The probability that an automobile being filled with gasoline also needs an oil change is 0.25;
the probability that it needs a new oil filter is 0.40; and the probability that both the oil and the
filter need changing is 0.14.
a) If the oil has to be changed, what is the probability that a new oil filter is needed?
b) If a new oil filter is needed, what is the probability that the oil has to be changed?

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
