The qualified applicant pool for three management trainee positions consists of seven women and six men.

(a) How many different groups of applicants can be selected for the positions?

(b) How many different groups of trainees would consist entirely of women?

(c) Probability extension: If the applicants are equally qualified and the trainee positions are selected by drawing the names at random so that all groups of three are equally likely, what is the probability that the trainee class will consist entirely of women? (Round your answer to four decimal places.)

(a) 286

(b) 35

(c) 0.1224

Step-by-step explanation:

(a) There are a total of 7 + 6 = 13 people to choose 3 from. The number of ways this can be done is given by

(b) If the selection were to consist of only women, then it will be from the 7 women only. The number of ways is then

(c) Any selection of 3 people is equally likely and each candidate is equally qualified. The sample space is space is equiprobable. The probability of selecting only women is

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
