Answer:

P(x = 0) = 0.004

P(x = 0) = 0.047

P(x = 0) = 0.211

P(x = 0) = 0.422

P(x = 0) = 0.316

Step-by-step explanation:

We are given the following information:

We treat a person who does not become a repeat offender as a success.

P(Success) = P(person who does not become a repeat offender) = 0.75

Then the number of people follows a binomial distribution, where

$P(X=x) = \binom{n}{x}.p^x.(1-p)^{n-x}$

where n is the total number of observations, x is the number of success, p is the probability of success.

Now, we are given n = 4

We have to evaluate:

$P(x = 0)\\= \binom{4}{0}(0.75)^0(1-0.75)^4 = 0.004$

$P(x = 1)\\= \binom{4}{1}(0.75)^1(1-0.75)^3 = 0.047$

$P(x = 2)\\= \binom{4}{2}(0.75)^2(1-0.75)^2 = 0.211$

$P(x = 3)\\= \binom{4}{3}(0.75)^3(1-0.75)^1 = 0.422$

$P(x = 4)\\= \binom{4}{4}(0.75)^4(1-0.75)^0 = 0.316$

PLEASE HELP!!

First, solve for x. Isolate the x. Do the opposite of PEMDAS.

2x + 4 = 8

Note the equal sign. What you do to one side, you do to the other.

subtract 4 from both sides

2x + 4 (-4) = 8 (-4)

2x = 8 - 4

2x = 4

divide 2 from both sides

2x/2 = 4/2

x = 4/2

x = 2

you know you're starting number now: 2

"then add it to two": 2 + 2 = 4
"then add it to ten": 4 + 10 = 14
"then subtract three": 14 - 3 = 11
"then add ten": 11 + 10 = 21

21 is your final answer

hope this helps
