Step-by-step explanation:
Given that a sign on the pumps at a gas station encourages customers to have their oil checked, and claims that one out of 10 cars needs to have oil added.
Since each trial is independent there is a constant probability for any random car to need oil is 0.10
Let X be the number of cars that need oil
A) Here X is BIN(4,0.1)

B) Here X is Bin (8, 0.1)

C) Here X is Bin (20,5)

That’s weird for the answer i got 10/33
Answer:
5y+3=7
Step-by-step explanation:
Answer:
=10t-6-7.5t = 6-0.5t
= 2.5t- 6 = 6-0.5t
= 2.5t+0.5t = 6+6
= 3t = 12
= t = 12/3
t = 4
Therefore the answer is 4
