An insurance agency has arranged the going with information relating the time of drivers and the mishap rate (the likelihood of being engaged with a mishap during a 1-year duration) for drivers inside that bunch.

Age Group Insured Drivers (%) Accident

Rate (%)

Under 25 16 6.5

25-44 40 1.5

45-64 30 2

65 and over 14 4

What is the likelihood of the accompanying? (Round all responses to two decimal spots.)

(a) A protected driver chose aimlessly will be engaged with a mishap during a specific 1-year time span.

(b) A safeguarded driver chose aimlessly who is engaged with a mishap is under 25.

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

(1) the number of various parcels are there for the coordinator ?

(2) what number diverse parcel are there if the subsequent subgroup is comprised of 4 individuals ?.

(3) what number diverse parcel are there if the fouth subgroup is comprised of 6 individuals ?

(4) what number diverse segment are there if the second and fouth subgroups have 4 and 6 individuals separately ?

(5) 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 class with n kids lines up for break. The request in which the children line up is arbitrary with each requesting being similarly likely. There are three children in the class named John, Betty, and Mary. The utilization of "or" in the portrayal of the occasions, ought to be deciphered as the comprehensive or. That is "An or B" implies that An is valid, B is valid, or both An and B are valid.

Give an articulation for every one of the probabilities underneath as a component of n. Work on your last articulation however much as could be expected with the goal that your answer does exclude any outflows of the structure ( )

(a) What is the likelihood that Betty is preferred choice or Mary is rearward in line?

(b) Explain the technique used to ascertain likelihood.

Prior to 1918, roughly 60% of the deceivers were male, and 40% were female. In any case, cattled rachers in the space have put forth a decided attempt to kill wolves. From 1918 present, roughly 65% of the two-timers are male, and 35% are female. Scientists presume that male wolves are more probable than female to get back to the space where the populace have been enormously diminished. Cycle three decimals:

a) Before 1918, in a ramdon test 11 wolves seen around there, what is the likelihood that at least 8 were guys?

- what is the likelihood at least 8 were females?

- what is the likelihood less than 5 were females?

d) From the time frame 1918 to introduce in a ramdon test 11wolves seen around there, what is the likelihood that at least 8 were guys?

- what is the likelihood at least 8 were females?

- what is the likelihood less than 5 were females?
