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
Archy [21]

Answer:

0.2916, 0.1488, 0.0319

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)

P(X=1) = 4C1(0.1)(0.9)^3 \\= 0.2916

B) Here X is Bin (8, 0.1)

P(x=2) = 8C2 (0.1)^2 (0.9)^6\\\\=0.1488

C) Here X is Bin (20,5)

P(x=5) = 20C5 (0.1)^5 (0.9)^{15} \\=0.0319

I already made an attempt at this question and I would just like to check my answer z = ?
Salsk061 [2.6K]

So we have the equation:

\frac{z+9}{4}=2.1

Then we need to multiply by 4 on both sides to get rid of the denominator on the left:

z+9=8.4

Then we subtract 9 on both sides to solve for z:

z=-0.6

Therefore the answer is z = -0.6.
