1. An occasion coordinator is planing a program for a gathering of 20 individuals who need to leave

on a touring trip. Because of space imperatives at the offices to be visited the orga nizer segments the gathering into five non-void subgroups. The quantity of individuals in the

subgroups may change starting with one subgroup then onto the next.

(a) what number various parts are there for the coordinator?

(b) what number various parts are there if the subsequent subgroup is made up

of 4 individuals?

(c) what number various parcels are there if the fourth subgroup is made up

of 6 individuals?

(d) what number various parts are there if the second and fourth

subgroups have 4 and 6 individuals separately?

(e) The coordinator picks a parcel of individuals at irregular. Discover the

likelihood that the quantity of individuals in the second and fourth subgroups

of the picked parcel are not 4 and 6 separately

An occasion coordinator is arranging a program for a gathering of 20 individuals who need to leave on a touring trip. Because of space requirement at the offices to be visited the association parcel the gathering into five non-void subgroups.the number of individuals in the subgroup may shift starting with one subgroup then onto the next.

(1) The coordinator picks a parcel of individuals at arbitrary .Find the likelihood that the quantity of individuals in the second and fouth subgroups of the picked segment are not 4 and 6 separately.

A clinical trial has been intended to distinguish the presence of a specific illness. Among individuals who have the infection, the likelihood that the sickness will be distinguished by the test is 0.96. Nonetheless, the likelihood that the test will incorrectly demonstrate the presence of the infection in the individuals who don't really have it is 0.04. It is assessed that 3% of the populace who step through this examination have the infection. (Round your responses to three decimal spots.)

(a) If the test regulated to an individual is positive, what is the likelihood that the individual really has the infection?

(b) If an individual steps through the examination twice and the test is positive the multiple times, what is the likelihood that the individual really has the infection? (Accept that the tests are autonomous.)

Elector turnout drops consistently as pay level decreases. The accompanying table gives the level of qualified electors in a specific city, ordered by pay, who reacted with "didn't cast a ballot" in the 2000 official political race. The table likewise gives the quantity of qualified electors around there, arranged by pay.

Pay

(percentile) Percent Who

"Didn't Vote" Eligible Voters

0-16 51 4,000

17-33 31 11,000

34-67 20 17,500

68-95 15 12,500

96-100 13 5,000

In the event that a qualified citizen from this city who had casted a ballot in the political race is chosen indiscriminately, what is the likelihood that this individual had a pay in the 17-33 percentile? (Round your response to three decimal spots.)
