Q1. (10 points.) Suppose that 10% of inmates in a large prison are known to be innocent. (a) (5 points.) A non-profit group randomly selects 20 inmates from this prison. Find the probability the group will find at most 4 innocent inmates. (b) (5 points.) If the non-profit group randomly selects the inmates until they find 4 innocent inmates, what is the probability that they selects less than 20 inmates in this process

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true

answer: the four apples you took away.

step-by-step explanation:

2 apples

step-by-step explanation:

taking away equals subtraction. 6-4=2
