An interviewer is given a list of potential people she can interview. she needs five interviews to complete her assignment. suppose that each person agrees independently to be interviewed with probability 2/3. what is the probability she can complete her assignment if the list
(a) 5 names?
(b) what if it has 8 names?
(c) if the list has 8 names what is the probability that the reviewer will contact exactly 7 people in completing her assignment?
(d) with 8 names, what is the probability that she will complete the assignment without contacting every name on the list?

a) b) c) d)

Step-by-step explanation:

Since we have given that

Probability that each person agrees independently to be interviewed =

(a) 5 names?

If it has 5 names, then the probability would be

(b) What if it has 8 names?

If it has 8 names, then the probability would be

(c) If the list has 8 names what is the probability that the reviewer will contact exactly 7 people in completing her assignment?

(d) With 8 names, what is the probability that she will complete the assignment without contacting every name on the list?

Hence, a) b) c) d)

answer: asdfghjkl,mnbv

step-by-step explanation:

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
