An air terminal limousine administration has two vans, the more modest of which can convey 6 travelers and the

bigger 9 travelers. Leave x and y alone the particular quantities of travelers conveyed by the more modest

furthermore, the bigger van in a given excursion, with the goal that a reasonable example space S is given by:

6 and y 17

9}.

Likewise, assume that peak all upsides of x and y, the probabilities equivalent. At long last: characterize

the occasions A, B, and C as follows:

A = the two vans together convey either 4 or 6 or 10 passengers*

B = the bigger van conveys twice however many travelers as the more modest van"

C = "the tV10 vans convey various quantities of travelers."

Ascertain the probabilities: P(B), and P(C).

question 62

An understudy advisory group of 12 individuals is to be shaped from among 100 first year recruits (40 male + 60

female), 80 sophomores (30 male and 50 female), 70 youngsters (24 male and 46 female), and 40

seniors (12 male and 28 female). Ascertain the accompanying probabilities:

(I) Seven understudies are female and 5 are male.

(ii) The advisory group comprises of similar number of understudies from each class.

(iii) The board comprises of 2 female understudies and 1 male understudy from each class.

(iv) The board incorporates in any event 1 senior (one of whom, in any case, will fill in as the

director ofthe council).

question 63

From a class of 50 understudies, of whom 30 are software engineering majors and 20 different majors, 5

understudies are picked indiscriminately to frame a warning board.

(I) what number such boards of trustees can be tormed7

(ii) what number such boards of trustees incorporate 3 software engineering majors?

(iii) I'Vhat is the likelihood that such a board of trustees incorporates 3 software engineering majors?

question 64

Leave S and L alone the occasions that a patient's visit to an essential consideration doctor's office results in a

reference to a trained professional and for lab work, individually. Assume that 0.257 P(L)= 0.35,

what's more, that the likelihood that there is a reference to neither an expert nor pinnacle lab work is

0.45. Compute the likelihood that there is a reference:

(I) To both a subject matter expert and peak lab work.

(ii) To either a trained professional or for research center work.

Clue. For part (I), use Proposition I(iii), and pinnacle part (ii): use Proposition 2(ii).
